Process

I applied through another source. The process took a week.

Recruiter call followed by a technical interview with one of the developers at the company.

It was really quick to hear back—the whole process only took about a week. Everyone was friendly, but they were seemingly looking for very specific answers that I didn't know.

Questions

Explain one technical challenge and then one piece of project work.

Best career move I've ever made

Senior Backend Engineer • Current Employee

Pros: The company has mission driven, super smart people, challenging work day to day, and it is one of the nicest groups of people I have worked with.

Cons: Planning cycles are a bit messy and there's unclear steer from leadership sometimes, but these areas seem to be improving.

Pros: Teams are empowered to organize themselves, so my experience might not reflect others. I consider this a pro. My team: - High trust - Flexible - Smart people. I've never felt like the smartest person in the room Code base/tooling is well supported. It's very easy to be a product engineer due to lots of the work done by the platform team.

Cons: Work can vary from super interesting -> downright boring, depending on the team. This seems to be a function of both 1) an established company and 2) the banking industry. Some things are used by millions of people a day, and that's super rewarding, then some things are not.
