So I initially had a call with the recruiter, then an interview with two engineers. I can't recall the exact questions, but I remember trying to solve something on a coding platform like Codility. One of the engineers asked a really specific question about microfrontends, which felt a bit too niche for the company's actual needs, but the other engineer helped calm things down. After that, I got a message saying I did well and an invite for the next interview, which I scheduled for two weeks out. But then, about a week before that scheduled interview, I got another message saying the next interview was a mistake. I don't really think it was a mistake; it felt like they had already decided on someone they interviewed earlier.

The interview process was smooth and professional, different from other interviews. It made me feel like a human, not just an application being processed.

Technical Coding Behavioral

Blacklane seems pretty on top of hiring, not just waiting around. The process can change depending on how you get in. Usually, it's a phone screen, then some coding homework, and finally an onsite with a few people. My manager found me at a Meetup and recruited me, and I had a lot of code on GitHub they could check out, so I skipped the coding challenge. I had a proper chat with him, the frontend team, and the engineering director, but it felt more like hanging out than a tough interview. I liked it. They're looking for team players who aren't difficult, and they're fine with hiring people who can learn and grow, even if they're not superstar developers.
