There were 3 rounds in first round is the written test for my role it contained some sort of by core question that was not that much difficult to crack and then 2nd round was technical round and 3rd round was HR round

Should have fundamental technical knowledge in the domain of Electronics and Software. Do you have prior experience in Electronics and also handle software. How to recover data from servers. Interview went good and the answers quite easier for me as I had prior experience in Software technology.
