Once the status of the team is confirmed and all problems are solved the manager will normally continue onto checking in with various departments and team leads, discussing any problems or jobs that need tackling. Once all the initial morning tasks are completed the data center manager will spend a good proportion of their day in meetings before walking around the facility making checklists for teams on things that need addressing and taking the opportunity to have quick stand-up talks with employees ensuring that they have the opportunity to inform you of any concerns or problems. Afternoons will then generally be spent in one to one meetings and emails before handing the shift over for the evening.
4. Can You Describe The Key Roles Within A Data Center Team?
A data center typically consists of three types of staff groups, the main section consisting of the data center team which is then supported by IT and security operations. The specific types of jobs that are included in a data center are dependent on the type and size of the facility. While the data center manager is the main person responsible for making sure that the process runs smoothly there is also a long list of people included in the team who all perform key roles.
Data center technicians – key members of the team who’s skill base cover a variety of tasks, technicians normally go where they are needed most in the data center often performing tasks like running cables and cross-connections and rebooting servers.
Developers – These are normally found writing custom software or integrating products into the data centers systems. They can also perform tasks like integrating customers’ account information into other systems.
Network techs / Admin – The techs are the people you need when the data center runs into technical difficulties. They can be found dealing with networking issues such as allocating IP address blocks and updating or fixing routing information.
Laborers – Generally people with the lowest skill sets but one of the most crucial parts of the team. They are normally used for loading and unloading at the receiving dock, cleaning or other repetitive low skill industrial tasks.

Guaranteed network security is essential for a data center, however with the technologies that hackers are using constantly updating and improving you need to make sure that your security is developing at the same pace. Which is why many companies are bringing in the Zero Trust Approach.
What exactly is the Zero Trust Approach? The security concept is based on the belief that a company should never automatically trust anything that is inside or outside the organization until it has been verified by the system. To develop an effective zero-trust approach it is important that every user is verified, every device is validated and that each individual’s access is limited intelligently.
The most important factor in a zero-trust approach is that it really is proven to help with security with breaches being 50% less likely than before. The security that is guaranteed from this model helps businesses to feel more confident in being able to bring new business models and customer experiences to the market. So as a data center manager developing a solid zero-trust approach seems like a sensible idea.
9. How Do You Arrange Your Staff Roster To Ensure There Is Coverage 24/7?
A 24/7 roster is a slow rotating shift pattern which generally used by having a total of four teams that all rotate with each other in three eight hour shifts. The four teams all rotate with each other every 28-days., ensuring that there is constant 24/7 coverage of the data center.
When arranging each team into a rota pattern it is important to ensure that there is the right team with the skills needed to keep the center running, making sure that there is an equal number of security guards, technicians, and labors, and so on to ensure that the teams created are effective. As the data center manager, you should also get to understand your employees so that you understand what employees would be most effective where.

It’s your job as the data center manager to make sure that they don’t start becoming unmotivated as having a junior employee holds the benefit of being able to train them with the exact skill sets you need as a company. If a staff member has been sidelined there are a few options you can put into place to try and rectify the situation. Firstly you could delegate specific roles that each team member has to complete and stick to, this allows the junior member of the team to feel like they are having a positive effect and direct involvement in the process. It’s also important that you get to understand the individual that way you can give them tasks that will develop the skills for the specific data management career they want. This also helps if you choose to buddy them up with a senior member of staff who is responsible for transferring skills. It may also be useful to talk to the rest of the team to find out what their concerns about the individual are and if you can solve them.
13. Please Explain What Activities Need To Be Considered During Data Center Migration
While data migration is often seen as been risky it is sometimes an essential process for companies that can’t be avoided. To ensure that the migration of data goes smoothly there are some things that you and your team have to consider. The first key consideration is the risks and how to reduce them. If there are any potential loss of data or server downtime they have to be recognized before the migration can even be considered. It is also important to consider that there could be applications that are decades old being migrated so all the systems and networks have to be understood so that it can be established what the best ways of moving each one are. Another key element that needs consideration when migrating a data center is latency, this is where the hardware can affect its performance through increased network latency. To limit the effect latency will have it is important to work out which programs work together. Once all of these have been considered and put into a plan the migration should run smoothly.
14. There Has Been An Insubordination Which Has Led To A Breach Of A Client Personal Information. Explain How You Will Handle The Issue As A Data Center Manager?
A breach affecting a client’s personal information is the worst possible kind as a long list of problems can occur for both you and the client.

However, as it is personal information that the hacker has acquired it is important that after notifying everyone effected that you file a report with the Federal Trade Commission as the leaked information could potentially lead to identity theft. Make sure that you also inform the local police and your company heads so that an investigation can take place. After following the procedure keep working with the client and inform your team on how to prevent any future cases from hap
15. What Is Data Center Containment?
Data center containment refers to the process of intending to restrict the mixing of different air temperatures. The separation of cold airflow from the hot airflow that is being created by the system should help to save the company revenue by reducing energy and leading to overall improved equipment performance.
The typical model for data center containment is to enclose the cold aisle with ceiling panels above, between racks and with doors at either end, the hot air that is then emitted from the server is pushed out of the aisle through a chimney system to prevent the air from mixing. There is also the option to use curtain systems, modular systems, and in-row cooling to create even more efficiency.
16. Explain What Critical Power Means
One of the worst possible situations for a data center manager is to go into critical power. Critical power can lead to a power outage that could affect hospitals, communication centers, colleges and more. It is the data center manager responsibility to ensure that you have critical power systems put into place just in case one of these situations arise.
Critical power systems are also referred to as being energy management systems that can detect outages which then works to start back-up generators so that mission-critical equipment can be provided with clean power. Extensive backup generators can always be found in data centers so that the customers housed storage, servers or communication equipment is kept safe and working.
17. What Style Would You Use When Approaching Managing a Data Center?

Coming into the company as a new employee means that you’ll have the benefit of looking at everything with fresh eyes and could offer a fresh perspective on issues. If you see something that you think could be improved then go ahead and suggest an improvement. While you may want to run in and start shouting orders at everyone and everything to make your workplace the best it can be it is also important to remember that you are a new person going into an already well-established team so don’t alienate your new employees.
Once you’ve established a secure bond with your team then it’s possible to start making suggestions for any procedures you feel need to change. Data centers are constantly looking to evolve to function in more efficient ways and so any changes are usually welcome. Some company procedure changes that may be welcome include environmental improvements such as upgrading the confinement aisles so that the system performs better in both terms of saving the company money and the systems running more efficiently. You could also suggest some promising investment opportunities or a different managing style.
30. Explain Your Process Of Managing Routing Cables?
When looking inside a well established and organized data center you’ll normally find a rather presentable space of rows on rows of clean racks and servers. While every data center has the ability to look like that, the results can be the complete opposite of the people who are responsible for maintaining the data center stop making a conscious effort route the cables in a clean and organized manner, instead leading to something that can only be described as a birds nest. This approach creates an unorganized appearance but is also unsafe, so as the data center manager make it clear to the interviewer that you would take ensuring that the standards don’t slip and that work stays safe and organized as one of your main work priorities.
31. Are You Able To Work In Odd Hours?
Data center managers are normally expected to work unsociable hours, you could be working long days from 8 am one day till 8 am the following morning if an important issue comes up that needs handling straight away. There are also on-call requirements which can happen at any hour of the day or night and if a catastrophic event comes up where all management will need to be involved then you’ll be in for a long night. Data center managers have to be contactable at all hours of the day, even when on vacation so make sure you are completely honest with the interviewer when discussing your availability and show them that you are 100% committed to the job.
32. How would you do the briefing on the next issue?
Data centers are made up of endless departments that all specialize in their own subjects so it is therefore important that communication within the company is kept flowing.

Communication within the data center is often left to help desk personnel so if you know about something that is coming down the pipeline let them know all of the relevant information that other departments may need so that their job becomes easier and you gain their support for being helpful.
33. Explain the Multi-tier Model?
Having extensive knowledge of what your working with is an important part of being a data center manager so be prepared for the interviewer to ask you knowledge-based questions, brush up on your technical knowledge before going, in case they ask you something like what is the multi-tier model? In which you’d then be able to reply with how the multi-tier model is a data center approach which is dominated by HTTP applications. The multi-tier approach uses web, application and database tiers of servers. The software that is used in the model runs alongside as a separate process and uses interprocess communications. There is also the use of multi-tier server farms which can provide improved resiliency and security.
34. Explain Why Do You Deserve This Position?
It’s important that you keep this answer focused on you instead of trying to drag down any fellow candidates as that may ring alarm bells and cause them to question your leadership skills. While there are lots of benefits that the job may give you we recommend staying away from listing all your benefits and instead let the interviewer know about how hiring you can benefit their company as a whole. You can also use this as a way to summarise all the previous points you’ve mentioned, bringing in personal traits alongside any previous management or data center experience you have. Desirable qualities that the interviewer may be looking for are things such as organization, leadership, expert knowledge of topics such as multi-tier models.If you think it will be able to make you stand out, it’s worth mentioning.
35. What Do You Believe Are Your Strengths?
It’s tempting to just list out all of your achievements and desirable qualities, but if they again don’t benefit the employer themselves then it’s not worth mentioning. Some personality strengths that the interviewer may be looking for is that you are a problem solver, a motivator and a natural leader as these would all benefit your performance as a data center manager. Make sure you consider the position and make a list of any qualities you have that can relate directly to the job. Most data center employers mention looking for previous experience or knowledge in service-level agreement management and data center infrastructure management before employing an individual. Whatever you believe your strengths are make sure you present them with confidence.
36. You Have Just Acquired A Company And The Data Center Is Getting All Their Assets. Tell Me How Would You Manage That?
Think about some hypothetical situations before going into the interview so that you can have a designated approach to tackling these questions. In a situation involving acquiring a company’s assets, it would be best to do your research on the company and its existing setup. There have been situations before where a new company’s virus-infested crypto mining setup has exploded across the established network so make sure you let the interviewer know how seriously you’ll take making essential checks on the acquired assets so that you can keep your company safe.
37. You Have The Job Of Reducing The Power Supply For Servers. What Would You Do?
With energy consumption becoming a major issue it is important as the data center manager that you look into ways of keeping the company up to date with modern times, which would also benefit you in the eyes of customers. Before the interview think about any current issues such as the environment which the interviewer could ask for your opinion on. Some of the examples you could for reducing the power supply for servers would be to wind down the number of physical servers which would majorly reduce the electricity use, with fewer servers running in the data center it would, therefore, be generating less heat which alongside helping the environment also results in more savings.
38. Do You Have Any Previous Experience In Using Patch Management?
Updating the servers is a crucial but time-consuming part of data centers. In facilities where there is a high number of servers to look after, going around to put every single one onto an update cycle is not an efficient option which has caused data center managers to start looking into ways to keep the servers current with security and performance updates leading them to use patch management. Patching is the process of repairing system vulnerabilities and is a necessity in a data center so having a good understanding of the process will be a benefit to the employer.
39. Explain What You Understand About Data Center Colocation And Cloud Based Services Such As Iaas
Colocation is a specific type of data center facility in which businesses can rent space for their data. A colocation usually provides the building, cooling, power, and security while the customer provides the servers and storage to go in the space. Some customers use the servers to run cloud-based services such as IaaS which is a virtualized computing resource that is provided over the internet. Do plenty of research to find out if the company you’re interviewing with provides this kind of service.
40. Top Level Management Has Asked You To Start Site Level Redundancy. What Would You Do First?
As the data center manager, it would important to start the process by creating a baseline by checking your already existing infrastructure. Once this is done it would then be a good idea to start planning out any upgrades that need to happen in the next 12-18 months. When all the figures are confirmed, you can then start shopping around for locations that can work alongside the original data center. Make sure you highlight that while you are an independent team leader, you will also involve others in the process to ensure the right result.
Overall, make sure you go into your interview with a good understanding of the business and confidently sell yourself with the ways you will benefit the company. Brush up on your technical knowledge and you’ll be walking out as their new data center manager.
