Candidate interview experiences
First-hand accounts from people who interviewed at Block.
Intern
I went through six interviews. The first two were after an online coding challenge and were done over skype and coderpad.io. The interviewers were nice but sometimes seemed distracted, and there were some skype issues. After that, I had two interviews on campus, which was great for collaborating in person. Finally, I had two more interviews on-site. During these, they not only looked at the problems but also connected me with other team members to discuss specific aspects of the work because of my stated interests. It was a really positive experience, and the campus was impressive too.
- One question involved a delayed process scheduler, which was a bit unexpected but not overly difficult.
Intern
Started with an HR screen, then a couple of hour-long phone interviews. After that, there were several back-to-back in-person interviews. Just a heads up, the interviewers talk to each other. Some interviewers were nice, but others seemed like they really didn't want to be there. It was an okay experience overall, especially since they seem to be really serious about hiring, but honestly, I wouldn't want to work with some of them just based on how they came across initially.
- Can you discuss specific cases and hypotheticals you've encountered?
- Could you walk me through a particular case?
- What would be your approach in a specific hypothetical situation?
Intern
I went through an initial engineering interview that was conducted over the phone. It involved a programming challenge where I shared my screen. The interview was scheduled for an hour, with about 45 minutes dedicated to a coding exercise and the remaining 15 minutes for a chat and for me to ask questions. I ended up spending most of the hour on the coding problem, and we ran a bit over time during the conversation part. For the coding part, I could use any programming language I preferred. They actually told me to pick the language I was most comfortable with, not necessarily one I'd use at Square. I was also permitted to use online resources like Stack Overflow or Google whenever I needed during the task. The atmosphere was pretty laid-back, and overall, it was a good experience.
- Could you build an interpreter for a basic assembly language?
