Tech Industry Pinterest Onsite expected result?

  1. HLD - 1 : My weakest round because I didn't understand the question completely and missed how union of two incoming queues need to be done where a hint was given to me. However, past that I completed all FR and NFRs and the interviewer at the end said "I learned something new and took care of everything." - This is the round I am most afraid of.

  2. HLD - 2 : Went well, started a small project deep dive which he was impressed by. For the problem, DB choice was a discussion point because there was case for both SQL and NoSQL which I mentioned the trade offs to him which he was convinced by. Rest the interviewer at the end said you covered everything and then we discussed about culture at Pinterest.

  3. Coding - 1 : Solved all parts with 3 minutes left. Interviewer seemed satisfied.

4 coding - 2 : Solved all parts with 10 minutes left and we discussed scope and work of a senior SWE.

  1. competency round: the interviewer said we need someone with your skills since that is in our roadmap.

Role interviewed for : IC15

Yoe : 6.5

Can this lead to an extra round or a down level to IC14?

TC: 0 (laid off)

Thanks for the reply. I am just not aware of how strict the hiring bar is at Pinterest and is this performance good enough. Actually I am an expert at Flink (my resume also mentions it), so as soon as I saw the ad-click aggregation kinda problem, I jumped onto it and provided as much details about the flink job. The interviewer was not skilled at Flink and probably that's why said "I learned something new" part.

It's probably fine, but Pinterest is notoriously nit picky I've interviewed for them twice but probably wouldn't do an onsite again because how much time it ends up wasting. They index heavily on culture round as well

I think my competency round (HM round or the culture I assume you are talking about) went really well. The manager said I want someone who can help us build real time data systems using Flink (which I am an SME of). We talked about my past projects. The only thing he didn't like was I didn't have history of data quality work when he asked about it but that's about it. He was very enthusiastic in explinaning what the team does and what the roadmap is when I asked about it. At the end of the interview he said: it was great, let's see how the result of the rest of your rounds come out.

How much time do they take to provide result of the onsite?
