Optym Senior Software Developer interview questions

Total - 5 rounds of interview. 3 Technical Interviews 1 Managerial Interview 1 HR round Interviews differ on the difficulty level from round 1 -3. 1st round of interview will be conducted by a Software engineer, 2nd round will be conducted by a senior developer and the 3rd round will be conducted by a engineering manager or a staff engineer.

The interview process included total 5 rounds, 4 being technical. The first round was a telephonic interview followed by a online test on hacker rank. The other technincal rounds were taken at their office. The level of questions was medium. They asked puzzles, Algorithms, DS, Javascript and angular related questions. I had cleared all the rounds and was given a positive feedback. But then they said that they need an immediate joinee and hence did not release the offer. This was not at all communicated earlier and it looked very unprofessional to not release the offer after clearing all the rounds.
