Process
Initially, I had a coding test. It just had one program on HackerRank. The next round was a phone interview. Again, another programming question. The interviewer gave me a call half an hour late for the scheduled time and then tried to finish the interview sooner, giving me 45 minutes rather than an hour, which left me with less time to finish the question.
Questions
-
Coding test: Split a hexadecimal string so that the results of the split are both perfect squares. Return the number of splits.
-
Phone interview: Write a program to update the board after every move in a Go game.

Apollo.io Work Experiences
- 1.0Remote But Toxic EnvironmentSoftware Engineer • Current EmployeeDecember 9, 2024Pros: Fully remote if that’s what you’re looking for.Cons: - Subpar work environment. - Terrible work/life balance. - High attrition. People will just disappear one day for one reason or another. - Bloated product and sloppy codebase.
- 5.0A lot of ups and downs, but heading in the right directionSoftware Engineer • Former EmployeeSan Francisco, California, United StatesNovember 10, 2020Pros: An open-minded leadership team weathered the company through multiple crises and steered the ship forward.Cons: Execs are young, and the company changed direction a lot when I was there. There were a lot of wrong senior hires who poisoned the culture. Probably not the best company I've ever worked for, but it doesn't deserve the hate from some other former employees.
- 5.0Empowering environmentSoftware Engineer • Current EmployeeNew York, NYJune 27, 2026Pros: The company gives engineers a lot of ownership and trust. You are encouraged to take initiative, make decisions, and drive projects end to end rather than just following instructions. The pace is fast, but in a good way. Teams move quickly, experiment often, and are generally open to adopting whatever tools, processes, or technical approaches are best for the company and customers.Cons: Nothing major comes to mind. Like any fast-moving company, there can be moments of ambiguity, but that is also part of the ownership and high-impact environment.
