How to Answer
To effectively answer this question, it is important to first understand what dimensionality means in reference to machine learning and how it can curse a project. As the number of features increases in comparison to the number of observations within a data set, some algorithms struggle in pulling correct data. Your job on this question is to talk about ways that you can avoid the curse in your designs. Some possible things that you may mention and describe are feature selection, correlation thresholds and variance thresholds.

How to Answer
As a software engineer, you are very familiar with the software development life cycle. For this question, your interviewer is looking to hear what models you have worked on in the past. While there isn't necessarily a right or wrong answer to this question, try to show your flexibility to working with different SDLC models by bringing up your past experiences. Then, show you have knowledge of different models like the waterfall model or agile model. It is also a good idea to use this question as an opportunity for you to learn more about Snapchat by asking your interviewer which model they work off of.

About Our Interview Questions

Our interview questions are created by writers, almost all of which, have a long history of recruiting and interviewing candidates. They do not necessarily have experience interviewing or working with companies, careers, or schools, in which they may write for on MockQuestions.com. We do, however, strive to match their background and expertise with the appropriate question sets found on our website.

Our careers, companies, industries, and schools may have duplicate interview questions and answers found elsewhere on our website. Specifically, our companies and our graduate school interviews. For these two, we use the industry in which we believe the company most well-represents and the graduate programs, as the basis for the interview questions and answers that generate for each company or school.

The intent of MockQuestions.com is for our users to build confidence for their job interview, by using our thousands of interview questions and answers as they practice and prepare for their interview. We believe, most of our visitors can become more likely to succeed in their job interview with hard-work and practice. We believe, the key to success is for our users to rehearse with our interview questions while using our answer examples as an idea generator for their own interview answers. We strongly want to discourage users from memorizing our answer examples. That is not the purpose of our website.
