Be Advised: HR will keep sending you "onboarding" emails, even before sharing the Offer letter. This is to keep you in the illusion of being selected. They put you on hold for 4-5 months and later drop your candidature. Even the official hiring portal will have a "Hired" Status mentioned throughout the process. All the best.
