Robert Bosch India Senior Java Developer interview questions

The interview process was fine. There were 2 technical rounds, 1 managerial round followed by HR round. But once the HR round was completed, i received a confirmation call saying that the offer letters will be rolled out by next week. But due to some reason even after 2 months i did not get any offer letter and that the HR do not pick the calls or reply to the mails when asked for the offer letter. Not expected such behavior from a reputed company
