Fulcrum Worldwide Senior Software Engineer Java Developer interview questions

I was approached by Reveille Technologies on behalf of Fulcrum, and the interview process was conducted by the Fulcrum team. I went through three rounds—Tech 1, Tech 2, and HR. I cleared them all and was assured that the offer letter would be released the very next day. They even mentioned that onboarding would start immediately. But then, out of nowhere, they called and said they were still waiting for management approval and asked me to wait. A couple of days passed—nothing. Then, like a broken record, they called again with the same excuse. And again. And again. It became an endless loop of false promises and frustrating delays. At this point, it’s beyond frustrating—it's outright unprofessional. Why put someone through multiple rounds of interviews, assure them that everything is set, and then backtrack with vague, meaningless excuses? If they weren’t sure, why say anything at all? This entire process has been a complete waste of time, energy, and patience.
