Intellifi (Canada) interview questions

3 / Three rounds of interview. 1st is HR via Phone call. 2nd is via Video call with the hiring manager. 3rd is Face to face Interview with Hiring manager, Team lead and the VP/Director.

Interview process is really pain in this company. They took total 4 rounds. 1st interview was HR, took 30 mins then 2nd technical with hiring manager took 1 hour, 3rd round technical took 1 hour, 4th round at Markham in-person took 1.5 hour. After 2 weeks, I got rejection without feedback. I requested the feedback but they denied. I spend so many hours on the interview and they simply so NO. I think there is budget issue.
