Interviewed for software engineer intern. Had one phone round followed by an onsite round which had 3 rounds. Pretty easy but in one onsite interview, the engineer kept telling me to code a brute force solution which was highly annoying. I was sitting and trying to come up with a proper algorithm - the question itself was not very difficult - but he kept interrupting and said algorithm doesn't matter. That one hour was a pretty subpar experience and I believe it might have affected the hiring decision.

Went in for an interview to the NY office and met with all members of the team at the time, including the COO. The entire process took approximately 3 hours and while everyone was super nice, I was exhausted afterwards. The questions varied from technical ones related to the field, to "How would you improve ZocDoc", to very informal conversation ones.
