Interview
fb recruiter contacted me for data science position. The interview process involves one or two phone interviews followed by an onsite interview .
Interview questions [1]
Question 1
1- 3 to 4 SQL question from the employee department with join, and conditional selecting
2- Stat question(OLS, assumptions, t-test, F-test in OLS? Are they both necessary or redunt? what metrics can you use, R squared and probability, what are the problems with R2? How does maximum likelihood relate to ols? Under what condition they are the same? If it possible by adding a feature r2 to decreased?
3- Machine learning: logistic regression vs linear regression, what is decision tree, how does it select feature? How does it decide to which feature to select? random forest what is the 2 element of randomness? What is the kernel trick in SVM?
4- Given a list and a target value, how to find the 2 element that the sum of them is equal to target? Space and time complexity? How to improve it? How the dictionary works?
Total 7 rounds: first round for resume screening, second for technical screening, then for on-site virtual with 4 interviews back to back, then hiring manager round after team matching and then salary negotiation with HR
