Tata Consultancy Services — regarding walkins

Address:

Indore, Madhya Pradesh, 452003

So my complain is regarding walking recently done. First they make the candidate sit almost 8 hours without single round attempt.
Second when they tierd of taking interview they just do formalities and reject a candidate.
Please its a request some candidate has dream to work and what they. Any tierd person can't do anything with fulll enthusiasm
If i say something its my apologies but its true
