RingCentral Tech Support interview questions

Delay on intial response from HR. Scheduled a HR screen interview. Did a test online. Then we scheduled an interview with hiring manager and a team member. Went very well in my opinion, interviewers were very nice and professional. After the interview, again radio silence. No response from HR after a few email saying they need more time. Eventually they called with an offer but for another position which they never actually sent out. Nope lol.
