Exponentia DataLabs interview questions

First it was telephonic interview (technical), conceptual questions about machine learning were asked. Also questions based on some practical senarios were asked. Then another round was with CTO of the company. He asked general project related questions. Then HR round. A data challenge was also presented.

One of the worst interviews I've come across. Interview process consists of 3 rounds. HR, Technical and CEO. Initially they will ask you to complete a case study/assignment accordingly you will be judged whether you deserve an interview. I cleared 1st and 2nd round and was informed to join from next week while the last round will be an informal round with the CEO. Post CEO interview, I was asked to appear for another round of interview (technical) reason being the panel wants to understand more about me. Post the interview, I was rejected and no reason was provided for rejection.
