I have been spending 1 month to go through their 4 rounds of interview. and the hr asked me availability for last round. before that, she also called me to confirm my salary expectation. over the phone, she said, ok, it is fine, under our budget and even promise to send the invitation right after the call. but right after it, she vanished into thin air. totally disrespectful and unprofessional. shame on them wasting people's time. highly unrecommended this company!!!! I have her reply as below: Your profile is through to the next round. Please help us schedule the subsequent technical interview with a few slots this and next week. P.S. - The objective of this round is to evaluate the candidate's ability to come up with solutions for typical data science problems. The candidate may talk about their data science experience first. Then please evaluate their approach and data science aptitude. The candidate may be asked to code part of a solution, and you may ask the candidate to provide a solution for an analytical problem (typical ones that we usually face at Tiger).
