Interview preparation tips for other job seekers - The Recruitment process is extremely slow and even weird like asking non-technical questions in technical rounds. The interviews were often rescheduled and mismanaged. The last round was in their office we reached before time and they had no clue that they had an interview scheduled. It began after two hours. Lastly they picked those candidates who had 0 technical knowledge in fact most of them had pretty bad interview experience since then could not answer any technical questions yet they were selected on the other hand those who could answer technical questions and had good interview experience were left out also the results came after a month leading me to believe there was something fishy
