Entelo Software Engineer interview questions

I was referred by a friend. The recruiter got in touch with me, sent an assignment to do. I completed it sent it back and was asked to schedule a time for an in person interview. I believe they were not aware that I was not from the US. I am not sure why that was the case as I did send my resume and it clearly stated where I was from. Regardless, when I asked if Entelo would be covering the cost of the travel for an in person interview or do I need to make arrangements. What happened next was a shock. I received an email from a no-reply account saying Entelo has decided not to move forward with my application. This was sort of disappointing as I thought I would really be a great fit. If they did not want to take care of the cost of bringing me in for a in person interview, at the least they could've used tools such as Google Hangouts or Zoom to connect and review my candidacy as they had already agreed to proceed earlier. Regardless, process was not really as I hoped but it is what it is.

I had two onsite interviews and a final phone interview with the CEO. The recruiter was very nice and helpful throughout the process. I brought and used my own laptop. The first onsite was a collaborative pair programming exercise with one of their team members for about an hour. I received feedback within a day. The second onsite was about 4 hours with five team members, lunch with the team, and the last few minutes with the recruiter. The interview with the team members consisted of pair programming, white boarding, and system design. I received feedback the same day and scheduled the final phone call for the following day. The final phone call with the CEO was for about 30 minutes. Within a couple of hours, I received a phone call from the recruiter with a verbal offer.
