Interview Preparation Tips

Interview preparation tips for other job seekers - This company has no minimum respect for the interviewee. Once I cleared first round of interview, they asked me to visit office for next round of interview the very next day. They tried to complete the whole interview process the same day along with salary negotiation. Once that is all done asked me to share documents so that they can work on offer letter and release it as soon as possible. But HR kept saying offer letter is in progress and will update you or call you once it is done. I tried to contact HR on call and also on e-mail but recieved no response let alone offer letter. It was waste of time, efforts and transportation money.
