Tech Mahindra Software Developer interview questions

There was an objective test of aptitude initially which was very simple and I cleared it. The next round was the technical interview on Java. I was interviewed in Hyderabad. They had taken interview for almost 1 and half hour on basic java questions and theory part of it. And there was this guy who joined in the panel and was asking me to write a code printing the prime numbers and when I had written the code he was saying you're not printing 1 which is prime. So these are the kind of persons they were interviewing me and I felt really bad for the company and left.
