I was contacted by a recruiter and set an interview date five days later. I had two virtual technical interviews, each lasting one hour with no breaks, although one was promised. Each interview involved two engineers, one conducting and one observing. In the first interview, I was only asked about my technical background. In the second, I was asked about myself – yes, that was it. We used HackerRank.com to code.

The first coding question was a mess. The recruiter couldn't explain himself properly and didn't understand C++, even though that was the full list of requirements for the job. The second interview part, however, was amazing. The person conducting was very professional and answered all my questions thoroughly.

I was unable to finish the first coding question due to the extreme confusion, but I completed the second.

Two days later, I received an email stating that they would not be extending an offer. I was also informed not to ask for feedback, as none would be provided.
