TCS — Did not process joining formalities

Hi Sir /Ma'am,

Off late! Just though of bringing this to your notice as I am being very helpless amid Covid'19 impact over job market.

So, let me put accross the actual grievance.

Last year in the month of Jan'19 to Feb'19 I was taken couple of interview rounds with TCS BPS Kolkata @ Candor.

1st Phase was taken by HR Recruiter- Kris Giri

2nd Phase Operations Round- Someone named Koel fro EON Project.

On 12th March 2019 I did received an e-mail stating "Pre-joining formalities- TCS BPS"..

I was completely overjoyed to see such mail as I was thinking like its a dream come true. Yes, every one thinks the same i[censored] gonna get posted in a supervisory role with such an amazing company TCS.

I did submitted all the neccessary documents required wherever applicable but as days passed nobody seems to be reply on my candidature.

My question to TCS is that :-

1) If a person has received pre joining letter then why he was not updated on the joining formalities?

2) Why HR Kris Giri seems reluctant and doesn't even bother to reply over calls or e-mail?

3) Is this the way HR of such a reputed multinational behaves?
