HCLTech Fixed Line Technical Support interview questions

We were left sitting in the reception for over an hour after the supposed time for the interview. It was a group interview, there were about 10 candidates being interviewed. We were brought into a board room and given a brief 20 question aptitude test to fill out.We were then asked to fill in forms detailing our personal information. After this we were brought to a workstation and each given the opportunity to do a touch typing test to show our wpm. Following this we were brought to the first floor and left in the floor's kitchen while one-by-one each candidate was interviewed for approximately 3 minutes in a meeting room next door. Some very brief questions about my general interests were asked and then we were each told we could leave. The following day (Wednesday) I received a call offering me a job, the caller couldn't provide me with any information on the status of the employment (fulltime/parttime) or the salary details. I was told I'd be starting Friday. I phoned on Friday to find out what time I should be in, I was told it had changed and it would no longer be Friday but in fact Monday. Same story on Monday. This repeated three times until I gave up on the position. Almost a month later I was called and told to come in the following morning. When I arrived in I found they'd hired every single candidate that day.
