I had been interviewed for the android middleware team and they arranged 4 rounds of interviews and that too on 4 different days and cleared first and second round and after that I thought it’s managerial round and again ended up with technical round and they asked c and python and after tht they started asking about C# wchich i m not aware of and infact I didn’t put anything on c# and completed 4 rounds and again TA told me tht they wanted to have one more round of technical round and I felt bit bad about the tedious process and later agreed for the 5th round technical interview but TA started telling me tht panel is busy and after few days no response from anyone seems like they ghosted the candidates and they just to kill the time
