I got selection mail. Had HR discussion and documents submitted on 6 December 2021.
I am trying to follow up on mails but no response.. Already 40 days passed and no offer letter roll out.. I got selected on the Hackathon test given on 21 November 2021...I am not sure whether I will get offer letter or not.. I am very much interested in the role.. I have around 2 years 11 month experience.. Please check and help me to get offer letter.. I never expected this much long waiting time. Connect me on [protected]
