First-hand accounts from people who interviewed at Crossbeam.
Software Engineer
So I got to the final interview and even got invited to the office for it. But then, 2 days later, I got a rejection. The email said they appreciated my time and effort throughout the process, especially since I made it almost to the end. They decided to go with someone else who was a better fit for the role. They mentioned the decision wasn't easy and encouraged me to apply for other positions. They wished me luck.
- Given an infix expression like ["A", "AND", ["B", "OR", "C"]], write a function to return the equivalent prefix notation, for example: ["AND", "A", ["OR", "B", "C"]].
- An expression consists of terms that are either variables, boolean operators (AND or OR), or nested expressions.
- You don't need to worry about parsing or tokenizing the input expression.
Software Engineer
It began with a really nice chat with a recruiter. Then I got a small coding task to do and send back. After that, there was a video call with two engineers where we did a pair programming exercise. The task was quite practical and didn't take too much time. The interviewers muted themselves a lot during the session and seemed to be giving feedback, but I couldn't hear it. The interview felt a bit disorganized and awkward because the interviewers seemed to want specific answers about the problem, but the environment they created didn't really encourage a good discussion. It felt pretty unprofessional. I got a rejection not too long after.
- Can you solve an algorithmic problem using a functional programming language?
Software Engineer
It begins with a recruiter screen to check if you're a good fit and to set up a time, then a system design interview with the CTO, followed by a coding interview, and a behavioral interview with a product manager. It's pretty typical for a smaller company that used to be part of EX-Google, Meta, etc. The whole thing takes about 4 hours with a short break in between, and it's all done over Zoom.
- What is your approach to designing YouTube?
