This happened to me. Several rounds of interviews with a well known colored-hat company, then... nothing. No response to follow-ups either.

What was especially frustrating to me was that up to that point, the tone of both the conversations and email exchanges was very positive and cordial. I would have expected a "Thanks, but no thanks" follow-up at least, especially considering I was an internal referral from a Sr. Mgr. But... nothing. Made my reconsider my view of that particular company.

Lots of companies are a mess internally.

If in 2-3 weeks you haven't heard from the recruiter, you should ping them back, if no response don't was further time and move along.

Interviews often seem like hit and miss. I would recommend training at geeksforgeeks.org just to refresh dynamic programming, etc. But beyond that you're better off applying multiple places.

When this has happened to me before with bigger companies, I finally get a rejection letter months after the fact. My guess is that it’s them hedging and not wanting to reject until they’ve filled the position.
