Interview was a fair game. I decided not to pursue and cancel final round as I felt the mode of interviewing was too stressful/too much pressure for me personally. I had extensive phone technical screen involving a lot of math and C++ questions. Was invited to in-person 7 or 6 hour interview. Parts of it were supposed to be video interviews with NYC managers and I personally do not wish to do video interviews, especially with people I will never have to directly work with. Also, I felt that having to find parking in a paid garage was too much trouble. The good thing, there was one hour lunch interview part and they were paying for this...not bad. Phone interview was with senior engineer/manager and he was kind of making it stressful--I didn't like it, prefer more calm and relaxed style of conversation. They gave me infamous Monty Hall probability puzzle/paradox during phone screen...I disagree with "solution"--as many mathematicians outside the US. I had written code proves that "US solution" is wrong. So, I stand by this and felt this paradox shouldn't have been brought up since it does not have accepted solution in Mathematics community across the world. I rate overall interview experience as positive as they offered to buy me a lunch, was showed basic respect on their part.
