WORST PROCESS EVER. WASTED MY 2MONTHS. They took my interview, did the negotiation etc. Made me wait for 1month for offer letter and kept asking me 100 times if I will join or no and I said "Yes". They kept asking for confirmation that I will join them and that I won't retain or join another company. I genuinely did not apply anywhere and was keen to join them. But at the last moment rejected the offer saying I am asking too much and that my company people are retaining and not joining so they can't trust me.
