I applied in Questrade directly. I got first phone call from HR, she discussed the opportunity and its requirements then she asked few questions just to make matching for their requirements with my skillset. After 1 week she sent an email to set phone screening interview. The interview was much detailed, the interviewer was a technical guy, and he explored many new technologies and my understanding about those technologies.

He also asked for older concepts and the applications of those concepts in real world. It was looking like a real face to face interview, and it took almost 1 hour. He told that HR will contact me if I passed through this phase. After almost 1 week I got an email from HR to schedule my face to face interview, after deciding time, I also got their background check forms to fill and carry with me at the time of interview.On the day of interview 2 technical guys were interviewing me, and they were not looking senior/experts. My interview went very well, and there was not many things that I missed and I was very confident about it.

They talked about Data Structure algorithm and later on discussed database queries. There was not a single question in DB side that I even had doubt, there were few scenarios that I did not cover in my algorithm. After spending 1 hour they went away to talk their VP, and later on came to me and said "VP is busy right now, we will let you know later on".After 2 days I got an email that I could not be selected. I am astonished why?

There was a tree and asked me to develop an algorithm to search the same boss for 2 employees. And during discussion the complexity was added.
