PayPal Data Scientist interview questions

It was a three round interview process. The first round is just a standard math test, 30 min test with a minimum score required to pass. Second round is a guesstimation test and brainteasers, took about 45 min. Not that difficult as long as you practice these kind of questions well in advance of the interview. Final round is a business case study followed by a standard interview. This took about 2.5 hours, a super long interview. The recruiters were great. I got personal calls from them throughout the process and they provide guidance and advice on the interview throughout

2 rounds:- - first round contains ml, stats and questions based on past projects - second round consisted of statistical and ds algo coding(easy - medium )level. in the end after taking the interview they said that your experience is somewhat less so try applying next year!!
