I applied from Canada as an overseas candidate.

After an online coding test and a technical interview with two engineers, I was invited to an on-site interview.

They covered the flights to and from Canada and my accommodation in advance.

Before the on-site, I checked their standing, and they said their impression was very positive.

The on-site interview included three sessions, one hour each.

After the on-site, right in the interview room, the recruiter told me that she could not get feedback from just one interviewer. She had already talked to the others, and they were trying to decide on the salary (she even told me the numbers they were considering).

Three days later, I received an email from her stating they were not making an offer because my technical skills were not strong enough.

Knowing that my on-site performance was better than the initial two interview results, I suspect that after initially telling me they would cover relocation expenses (such as flights, moving of belongings, initial accommodation for a few weeks, etc.), they simply did not want to do so for someone coming from Canada.

A good process until the end, which left a bad impression.

Simple coding question.
