Tata Consultancy Services Entry-Level Software Engineer interview questions

A recruiter reached out to me on LinkedIn and asked me for my transcript. She told me the interviews would be the coming Saturday and someone from HR would email me to schedule. The next day I received an email to confirm a time for my interview and I replied with a time that worked for me. I never got an email confirming the time and they never called me for the interview. The entire process seemed very unprofessional and if I had received an offer from this company I would not have accepted.
