ProcDNA Intern interview questions

Had a great experience, it was on campus drive in Thapar University. There were 4 rounds.All rounds were elimination rounds. 1st round was an online test, and the difficulty was okay, not that hard, but time was the major crunch. 2nd round was offline case study round; cthe ase study was actual business problems in the market, sothe difficulty was good enough. 3rd round was technical interview which was completely based on CV and puzzles and case study just wanted to test your problem solving skills. And 4th round was HR round and unfortuanately I did'nt got selected till HR rounds of interview.
