Fanatics Senior Software Engineer interview questions

Interview process was fairly easy. Applied through their careers portal. Recruiter called me and marketed the company for 20 mins and then asked me to introduce myself in the rest 10 mins, and then mentioned that he will get back after speaking to hiring manager. Reached me back in 10 days and scheduled a 30 mins technical call with hiring manager where I was bombarded with back to back technical questions on my background experience. The feedback of this round was excellent and so I was moved to the next 1 hour technical round with two senior team members(which was supposed to be coding round as per manager's feedback). But this round consisted of the same questions as the manager, just a bit deep diving. Coding question was asked only after one hour was over as extra time, which was very easy.

After initial discussion with HR who sits in usa, I had 3 rounds of interview with a tech lead, hiring manager and company's cto. All interviews went very well and I was selected. HR then scheduled a meet regarding any offer I have. She happily said that they would be matching my offer. I was happy too as Fanatics is a big name and I was happy that I was selected for that. But after that HR went silent for 2 weeks without any communication. I asked for update on the offer through mail, but no reply . After 2 weeks, HR informed me that they are moving forward with other candidates. HR already knew the offer I had in hand. Still she continued with the interview. And then in the end rejected me, without any proper detail even if I successfully cleared all tech rounds. This is the worst kind of behaviour I've observed from HR of a company. If you don't have the budget, tell this directly to the candidate in the first HR discussion only, why wait so long just for the sake to reject the candidate at last.
