Tata Consultancy Services Sr. Software Engineer interview questions

waiting in the meeting room for approximately 2 hours with no time line. A group of people asks for the technical name on the resume and explains the meaning of the technical name.

It was a scheduled drive at Thane location. Around 100+candidates were there for Java profile. I reached there at 10.15Am. But I was called up for the first round at around 4.45PM. In mail they had mentioned the profile for backend developer. But interviewer panel were expecting candidate having exp in front end technology. This was such a terrible experience and waste of time. All I waited just for 10min of interview after 6hrs of waiting time. Atleast they should filter candidates based on telephonic interview and atleast should mentioned the exact profile. Worst interview experience ever.
