Tata Consultancy Services Senior Developer interview questions

Multiple Rounds of interview, Process wasn't clear. Improper communication. They don't respect your time. It happened literally 3 times. I joined the virtual interview using the link they sent me. There wont be anyone, I waited there for more than 20 mins to know that no one bothered to join nor inform me. And later i get the email saying your interview is rescheduled. This is ridiculous of them and audacity and never respect the candidates. They have a standard set of questions to test your ability to write software and each time the questions won't differ much.

Simple process. On time joined have 3 people including hr and developer. They asked about my experience and technology. Then I replied and it's over next day I got to know that I have selected but after that I did not get offer letter
