Question 1
Given constraints on correlation between three R.Vs, bound the correlation between one pair of them.
quite unorganised interview. had a face to face interview with 2people from the company. They asked a lot of questions to get some colour rather than really trying to hire someone.
Had a recruiter phone interview then two technicals followed by an onsite final superday, much more technical than other firms and more strict. Flew out to new york for the onsite.
