Recruiter called me 15 min after our scheduled time. Did not apologize and did not even ask if it is still a good time to talk. Instead they rushed straight into talking about the company and asking me questions. They also mentioned that they’re interviewing candidates for this role in case their intern does not accept the offer. Told me they’ll follow up by the end of the week but never heard back.

One of the Recruiters contacted through email, had 20 mins call. We setup 1 hour telephonic technical interview (coding, data model, queries, etc). Received an email a week after for On-site interview. 5 On-site interviews as follows: 1. Introduction A Senior Software Engineer explained about Collective Health model. It was very informative. 2. Values Interview Interviewer didn't seem interested at all. There was a very little eye contact from the interviewer. Also, interviewer seemed rude, not very friendly which really irritated me. Obviously couldn't answer properly. I like to work in a friendly environment so, decided NOT to JOIN Collective Health 15 mins through this interview. 3. Coding Interview Two Software Engineers took this interview. I was getting interviewed for their team. They both looked happy and interested interviewing their future co-worker. Not a typical DS question but I would say straight forward medium level question, one can solve it thinking out loud which was expected by interviewers. 4. Architecture Interview Two Software Engineers from some other team took this interview. It was similar as Values interview. Interviewers didn't seem intersted interviewing me. They were rude, no/missing eye-contact, asked counter questions(seemed like they wanted to build something which would work no matter what goes wrong). I did mess-up data model a little but if I were in a right state of mind I would have come-up with better one. Then came the API part, steps to implement Robust API for notification. Provided solution with which they weren't happy. Basically, per interviewers Implementing Robust API means user should be notified no matter what happens. It's like sender expects USPS/UPS to deliver a mail to a right receiver even if provided receiver's address is wrong. At least this is what I got from discussion. Usually I ask for the right/expected answer in the end but this time I didn't care to for ask it. 5. Hiring Manager Interview Talked about work, team, interests, and stuff. Not worth taking a time-off for on-site interview.
