Typically I never see an interviewer turn up on time. I mean it's like you spend an hour or more beating the traffic, and then locating the venue, and then trying to find a place to park your vehicle. After all the trouble, you find that the interviewer is "busy" so please wait.
Sometimes the wait turns out so annoying, when you see the staff there running around busy or rather "looking busy". No one bothers to answer your query, they are just running around.
Some interviewers just try to bully you. Even when you are right, they are hell bent on proving you are wrong. Of course there are some who will try putting you down as much as they can, to the extent of destroying your confidence. That itself is a red flag never to join that company.
Worst experience I had with TCS, the panel was filled with some old uncles, who kept asking everything except what was related to my field. Yeah once was asked about bridges too.
The walk in drives are the worst of the lot. More often than not chaotic and messy, stand in long Qs, some volunteers trying to look important. And endless wait for your turn. Go to one of them be prepared to spend all day there.
Do share your interview experiences.
