The interview was a fair game. I decided not to pursue and canceled the final round as I felt the mode of interviewing was too stressful and applied too much pressure for me personally.

I had an extensive phone technical screen involving a lot of math and C++ questions. I was invited to an in-person, 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 was that there was a one-hour lunch interview part, and they were paying for this – not bad. The phone interview was with a senior engineer/manager, and he was kind of making it stressful. I didn't like it; I prefer a more calm and relaxed style of conversation.

They gave me the infamous Monty Hall probability puzzle/paradox during the phone screen. I disagree with the "solution," as do many mathematicians outside the US. I had written code that proved the "US solution" is wrong. So, I stand by this and felt this paradox shouldn't have been brought up since it does not have an accepted solution in the mathematics community across the world. I rate the overall interview experience as positive as they offered to buy me a lunch, and basic respect was shown on their part.

Monty Hall paradox... I still disagree with their (nearsighted) solution.
