Zocdoc Principal Software Engineer interview questions

Skype interview for 45 minutes, 1st in-person for 4 hours with 4 engineers and 2nd in-person for 1 hour with CTO. The skype and CTO interview are most challenging. Be prepared to get to the white board and write code. I got a lot of blank stares for using ansi sql and scala syntax. They are used to t-sql and whatever microsoft uses to write code

Their recruiter reached out to me on LinkedIn. I am a local candidate, so I only had 1 phone interview before the onsite. Their office is located in a cool building in a cool neighborhood. The recruiter asked me to allocate 4 hours for the interview loops. Three interviewers were a engineering director, a principal engineer, and a more jr software engineer. All of them are very professional, which made the whole experience very positive. After 3 rounds, I assumed it was done according to info here, I was asked to stay for the 4th round. Then about 5 mins later, the coordinator stopped by saying the final interviewer was stuck at a meeting. About 1 week later, I was told no offer. They encourage me to re-apply after xx months time frame (i always find this part amusing). My overall impression about zocdoc and interview are: - a solid startup with a nice business model. - their technology, at least for the team I was applying, was out of date. yeah, and it's a .net shop. - a couple of onsite questions are considerably harder than phone interview. probably because it was a 'principal' position.
