LogicMonitor Senior Software Engineer interview questions

HR scheduled my all technical interview rounds on same day. I reached out at 11 AM Started first round of technical interview, then said wait some time. Then HR scheduled second round of technical interview, it's completed then another person came and took 3rd technical interview and he took whole interview and said wait for some time. Then another person came and took 4th round of discussion. and he said wait some time. After some he came and said HR is not here she will call you for next step, but no further updates yet.

Appeared for 1st tech discussion that went well. HR confirmed that they will schedule next round shortly and never came back. Neither any clarification on further process. No reply to any of my mails, atleast HR should clearly convey if hiring is frozen or whatsoever. But they simply choose to ignore any conversation with candidates when there is no update or any negative feedback. HR should do their work properly and candidates are open to take negative feedback too. Just not waste anyone's time and effort that has put in attending interview.
