Bluecrew Software Engineer interview questions

Applied directly to their job posting. They responded many months later. Their first round is a 45-minute call via Microsoft Teams. The first 15 minutes of the call is of your background, describe a technical project you worked on, then 30 minutes coding in a shared coding environment, and then any leftover time for questions. No other preparation details beyond that were given. I had to provide my availability manually. There was no option to select my availability from a calendar like most. This feature for candidates is common with companies that use the Greenhouse ATS. I received no more communication from them or a confirmation of submitted availability. A week later, they told me I missed the interview. It turns out the interview was scheduled and I was never notified or emailed. An apology was never offered. The interview was scheduled during a time that was outside my availability and days after the time I specified a week earlier.

Recruiter intro - get to you know you and make sure tech is the right fit. Technical - questions about resume and then a technical challenge involving finding a given number in a matrix of numbers.
