2. If You Get This Position At Snapchat, Which Data Cleaning Procedures Are You Comfortable Using? 

     To enhance data quality and increase the productivity of a system, a data analyst must use data cleaning methods to ensure efficiency within the system. In my previous position, I used a systematic technique in data cleaning. First, I would remove duplicate and irrelevant observations within the data. Then scan the data to take out extra spaces, eliminate duplicate data and convert numbers stored as text. With these steps, I am confident that the data is clean and accurate. However, I am open and willing to learn and adjust to the current methods at Snap Inc. 

3. How Would You Describe The Curse Of Dimensionality? 

To understand the curse of dimensionality, we need first to understand dimension reduction.   Dimension reduction is a method of converting higher-dimension datasets into lesser-dimension datasets while retaining similar information. Dimension reduction is widely used in machine learning to help obtain better-fit predictive models to solve regression and classification challenges. 

     For instance, dimension reduction helps deal with high-dimensional data like signal processing,            speech recognition, or bioinformatics. It is beneficial in data visualization, cluster analysis, and noise reduction. Managing high-dimensional data can be challenging in practice, a process commonly referred to as the curse of dimensionality. An upsurge in the dimensionality of the input dataset can complicate any machine learning algorithm. 

4. From Your Experience, What Are The Benefits And Drawbacks Of Applying Dimensionality Reduction? 

     Some of the benefits I’ve noticed while applying the dimensionality reduction technique include          the following: 

  • There’s minimal computation training time needed for reduced dimensions of features.
  • By taking care of multicollinearity, dimensionality reduction takes care of any present redundant features. 
  • Reduced dimensions of features of a dataset are beneficial in quickly visualizing the data. 
  • Reducing the dimensions of features also decreases the storage space for the dataset. 

     Although applying dimensionality reduction has significant benefits, it also has drawbacks,      including data loss. Also, the principal components required in Principal Component Analysis dimensionality, are sometimes unknown. 

5. From Your Experience, What Approaches Of Dimension Reduction Are You Familiar With? 

There are two ways of applying the dimension reduction technique. These are feature selection and feature extraction. Feature selection is the process of picking a subset of the relevant features while eliminating irrelevant features present in a dataset which helps build a highly accurate model. On the other hand, feature extraction transforms a space with many dimensions into a space with fewer dimensions. Feature extraction is beneficial when you desire to retain all the information while using fewer resources when processing that information. 

6. Which Feature Selection Methods Are You Familiar With? 

Feature selection has three main methods: Filters, Wrappers, and Embedded Methods. In Filter           Methods, the dataset is filtered, and a subset containing only relevant features is picked. Correlation, ANOVA, Chi-Square Test, and Information Gain are standard filter methods techniques. 

Though the Wrappers Method has a similar goal as Filters Method, the process incorporates a   machine learning model for its evaluation. In this method, some features are fed to the machine learning model to evaluate its performance. Feedback from the performance will help decide whether to add or eliminate those features to help improve the model’s accuracy. While this method is more accurate than the Filters Method, it is more complicated to operate. Some common Wrapper Method techniques include Backward Selection, Forward Selection, and Bi-directional Elimination. 

In the Embedded Method, the process examines different training iterations of the machine learning model. It also assesses the significance of each feature. Elastic Net, Ridge Regression, and LASSO are some standard Embedded Method techniques currently in use. 

7. Which Familiar Feature Extraction Techniques Do You Know? 

     There are many common Feature Extraction Techniques, but those that I know of include the   following: 

  • Kernel Principal Component Analysis
  • Quadratic Discriminant Analysis
  • Linear Discriminant Analysis 
  • Principal Component Analysis

8. How Can A Machine Learning Engineer Prevent The Curse Of Dimensionality In Designs? 

Usually, a database containing many input features complicates the predictive modeling task.

Since it becomes difficult to visualize or predict specific datasets with multiple features, a dimensionality reduction technique is required. 

There are different techniques of dimensionality reduction, including: 

  • Random forest
  • Score comparison 
  • Forward selection 
  • Backward elimination 
  • Principal component analysis 
  • Missing value ratio
  • High correlation filter 
  • Low variance filter 

9. If Hired For This Position, Are You Confident In Handling Project Management Responsibilities For New Software Development? 

My career in software engineering started from an entry-level position which has given me exposure to what happened in different departments within this industry. I’ve also learned so much from experts who have been instrumental in helping me sharpen my technical skills.

I can conduct a feasibility study on a project and estimate the time, cost, staffing needed, and overall planning requirements. I have been in charge of a department supervising teams tasked with handling different projects for multiple clients. 

10. Which Sdlc Models Do You Have Experience Operating? 

Some SDLC models I am familiar with include agile, waterfall, iterative, spiral, and V-shaped. I had extensive experience working with the waterfall model. In my previous role, I was able to complete complex projects. The waterfall is a reliable model since its approach eliminates mistakes resulting in pervasive documentation development. The method benefits developers who may need to work on the project in the future by saving time writing everything down. I love this method because it is simple and easy to understand, making it perfect for smaller projects where requirements are straightforward and not equivocal. 

Previous experience gives me adequate skills and flexibility to handle different SDLC models. For instance, in my last role, I used waterfall and agile models in most projects that I was in charge of. However, I am very interested to learn more about the models used here at Snap Inc. 

11. Do You Have Any Experience Handling Software Maintenance? 

There are four types of software maintenance processes. The one I rely on the most is adaptive maintenance. In my previous contract, I was in charge of banking software, where I regularly helped perform system maintenance for changes in currency. To ensure success, I did plenty of research and approached end users for feedback. I believe that I am the right candidate for this role at Snap Inc. as I have experience performing preventive, corrective, and perfective maintenance procedures on various applications.

12. Share An Instance Where You Utilized Universal Design Practice In Your UX Or UI Designer Task And Why The Process Was Significant

From my experience as a designer, I believe a product needs to be practical and accessible to many end users. The success of any app is its universal design, which will allow it to reach people who previously may not have had access to the service it provides. In my last role, I created a product targeting a more mature audience. With this development, business owners quickly reached the target market using the app making it a very successful project.
