In my last job, I worked for one of the biggest marketing companies in the country. I had a great experience and got the opportunity to learn more about this industry. However, I didn’t have much experience initially and therefore struggled with some of their systems and software and didn’t grasp some operations. I had to work twice as hard, asking for help and practicing every day to familiarize myself with all the essentials in the organization. At one point, I had to stay behind after everybody had left to better myself. My hard work paid off, and in 2 weeks, I was on top of the game. I am glad that the top management understood and gave me a chance. I did not disappoint afterward.

5. Briefly Describe Your Experience

This is my fifth year in statistical analysis. I have had the opportunity to work in different industries and therefore experienced statistical analysis from different perspectives. I have vast experience using several tools and software and have also learned to critically analyze data without any bias or expectation, thanks to my experience with different fields. At one point, I was the chief statistical analyst for Jack and Jones Insurance Firm and won the best employee of the year twice. The company rewarded me by sponsoring my Masters in Applied Maths degree, helping me advance in this field. I am confident that I will do an excellent job based on this experience.

6. Mention Your Daily Routine

My day revolves around retrieving, gathering,  organizing, analyzing, and presenting data. This varies depending on the type of data I am dealing with, as some are more intensive. However, some of my daily roles include using data to spot trends and patterns, finding useful insights to recommend to clients, reporting, collaborating with others across different departments such as managers, executives, and data analysis teams; developing and implementing data collection strategies, creating spreadsheets, presenting reports to the relevant authorities such as product development managers and stakeholders and evaluating the success of different decisions.

7. Mention a Strategy and Mindset Required For this Role

The best strategy for any statistical analyst is observing proper organization and prioritization of work. This job can get bulky, intensive, and challenging, making it unachievable without these strategies.

10. Mention a Time You Failed in this Role and the Lesson You Learnt

I had made it a habit to go through my work twice to weed out any errors and ensure that everything was in order. However, on this particular occasion, I was in a hurry and therefore submitted my work without reviewing it and ensuring that everything was in order. I received a call from the supervisor while meeting a client that my manager had spotted a costly insight error. I was summoned and had to explain and make the necessary corrections. This experience taught me to leave nothing to chance and always review my work despite the surrounding circumstances. I would rather ask for more time than finalize a report or submit work that hasn’t been reviewed yet.

My manager was pleased and, together with the company, awarded me a paid two-week vacation to Bali. Even though I have won several awards afterward, this remains my best. It evokes fond memories.

13. How Do You Normally Ensure That You Don’t Make Mistakes?

I normally maintain a keen eye when going about my work which helps me identify mistakes and make necessary corrections. I further go through my work thoroughly after completion to ensure no flaws. I may also ask a team member to go through my work once done. I made a costly mistake when I was a rookie, which taught me the importance of thoroughness and a keen eye during statistical analysis.

14. Can You Work Well Under Pressure?

Absolutely. I believe that pressure brings out the best in me, given that I am fueled by challenges. I can cope in extremely stressful situations and meet tight deadlines. I know how to organize myself and prioritize my work during such times, which has helped me get out of tight situations successfully. My years in this field have also helped me adapt to pressure. I believe that I will do a good job if given a chance.

15. Have You Ever Had to Complete a Project on a Tight Deadline?

Yes. Several times. However, the most remarkable experience was when a client made a last-minute change when I was almost done with the project. Even though we negotiated new payment terms, I had to start over again to incorporate the changes and had only two days to deliver, when in essence, I needed more than a week. I worked overtime, at times deep into the night, got as much help as I could, and managed to finish just in time. This remains one of the most challenging projects I have had to work on.

16. How Well Do You Work in Team Settings?

Exceptionally well. I understand that a statistical analyst must work with others, and as a person who has been part of teams in my whole career, I believe that my team working skills are apt.

I am proficient in Excel, which helps me in making tables. I also know how to create databases in Access and have vast experience with several data management software and mining algorithms. However, I am still open to exploring other software and tools if given a chance.

18. What Do You Normally Do Before Starting a New Project?

I normally take some time to reflect on the project and understand it before anything else. This helps me understand the objectives of the project and the problems I am likely to face. I also reach out to the client if I have any queries. I then sieve the data, understand its origins and test its reliability before finally checking whether the project is viable or not. I tailor all my activities around the deadline.

19. What are Some of the Statistical Methods You Use in Your Work?

I use a number of statistical methods, which are also beneficial for data analysts as they go about their work. These are the Bayesian method, imputation, simplex algorithm, Markov process, mathematical optimization, spatial and cluster processes, rank statistics percentile, and outliers detection.

20. What are Some of the problems you face when going about your job?

There are several problems that we face as statistical analysts. Some of the most common include duplicate entries and spelling mistakes, which can interfere with data quality, incomplete data, poor quality data, especially when extracted from unreliable sources and varying in representation by data obtained from several sources.

21. How Good are Your Excel Skills?

I am proficient in Excel. I understand its importance when dealing with data, and therefore, I had to work twice as hard to master it. It plays a huge role in my work. I can create tables, manipulate data, and perform various activities with it.

22. Mention Some of the Advantages of Version Control

Version control comes with several advantages. However, the most common are: it allows people to compare files, identify and differences and effortlessly merge the changes; stores and maintains several versions and variants of code files; maintains the history of the projects files and helps track application builds.

23. Define Normal Distribution

Normal distribution, also known as the Gaussian or Bell Curve, is a probability function that measures variables’ values distribution, which is normally symmetric. It also describes the distribution of the values of these variables. It is also worth noting that the probabilities for these values are normally further away from the mean.

24. What is Your Greatest Strength as a Statistical Analyst?

My greatest strength as a statistical analyst is my organizational skills, which allow me to get things done on time. I know how to prioritize tasks and make the right follow-ups. I normally plan out my day initially, detailing what is urgent and needs to be done first. Proper organization also helps me deal with the pressure of being a statistical analyst. I believe that these skills will help me work well and contribute positively to this workplace.

25. Differentiate Between Variance and Covariance

Variance and covariance are some of the most common statistical terms. Variance refers to how distant two quantities are with a mean value. It only allows you to know the magnitude of data spread around the mean. On the other hand, covariance shows how two given variables are likely to change together. Unlike variance, it offers both direction and magnitude. All in all, these two show how different quantities vary in respect to one another.
