All the people at the company were very nice, though the interview process took longer than I expected due to interview cancellations. The phone screen questions were not too easy and not too difficult, but they were optimized for higher-level languages (like Ruby). Not everybody in the company knows C++, so it was very hard for me to solve the problem in C++, and the interviewer didn't understand why it took me so much time or why it's harder to debug problems.

After the interviews, I was paid for a one-week work trial. I had lots of problems setting up the system, which took too much time, and I didn't get much help as the only person who knew how it works was working remotely that week. I was expected to work independently, as I applied for a remote job (where the bar is higher).

I believe there was some luck involved as well, but I felt that the people there are very smart and hard-working. I had a good time there, and everything was paid for me (the overwork time as well).

Given bids/asks and orders, what are the matched orders?
