Questions focused on ability to build high performance and scalable application design. Heavy emphasis on writing lower level algorithms in C#. i.e. data structures.

I applied for Principal Software Engineer for GitHub Copilot. A recruiter reached out to me by email to schedule the first screening round asap. I was surprised, because it isn't how it worked few years back - there was an introductory screening call with recruiter first. In a few days the recruiter called me from abroad on my mobile phone to discuss the interview process and expectations. Compared to few years back, information shared regarding rounds wasn't as detailed, but basic information was provided. Few years back I received information on what soft skills they are looking for in each round and that could be used to prepare examples for discussion. It was not the case this time. We did the screening round, the interviewer was based in US, it went well, a discusssion mainly about past experience. A week later, recruiter phoned me to regrettably inform me that they have decided not to move forward and provided feedback why. They reportedly saw a gap in incident handling, which looks like proxy reason to me/misunderstanding as I have really solid experience in making sure we have a quick resolution, root cause analysis and prevention. The job opening was generic, mentioned many programing languages but it turned out they use almost exclusively Go on the project. I did specifically open this question on both screening calls to judge tech fit. This, together with the solution running in Azure, where I lack experience was probably the main reason for rejection. I would have given this a positive rating if the process was as organized as few years back. It may take a few years until I apply again as the site serves as a junkyard for projects they don't want to do in US and I'm not interested in that.
