Got invitation to coding assessment on June 2. 3 Questions on Codify. Two of them were super easy. The last one is related to graph, which I didn't get full score in correctness and performance. Overall score was 92%.

Phone Interview (1h):
I got invitation on June 5 and it took place on June 10.

  • Tell me a time you not only met a goal but also exceeded expectation.
  • A tough or critical feedback I received.
  • Tell me a time you didn't meet a commitment.

Behavioral questions:

  • A complex problem that was solved in a simple way.
  • A difficult problem to solve.

  • get all messages for a user
  • delete messages that are older than 7 days

Behavioral questions:

  • A time I made a decision without data.

[Round 5(Manager)]

This round was all about behavioral questions. All questions he asked, I haven't seen them before. So I can't remember a lot. The only question I remember is the worst code review that I gave and received. Also, he went quite into details and asked a lot of follow-up questions until I was wordless.

Summary:
I performed bad and I got rejected. No surprise.
I can't give suggestions here because I failed. But prepare your examples/stories in great detail. They could ask anything about it.
