X Senior Software Engineer interview questions

HR screen, standard coding interview. Moved on to the final round. The interviewers could not have been nicer, for the coding or the system design round. The final behavioral management interview was alright as well - they really dig into your past. What annoyed me the most is the recruiter ghosting me. I understand not getting the role, some explanation of why or closing out the loop seems the least courteous thing someone could do. I do not like the whole "let's prep you for the final round of interviews, and make a great candidate experience" schtick, and then proceed to ghost the candidate. Really, a large pool of candidates is fantastic for the company, but I would not imagine anybody would like to simply be left in the dark after preparing for weeks and weeks to hear nothing. Super disappointed more than anything.

First HR call, seems like a very good match with the position, then 60 mins phone screen interview with a pretty standard leetcode medium question, bug free and had good feedback from the interviewer, then the next day received a moving forward email with no surprise, totally waste of time.
