Software Engineer Interview Experience - Madison, Wisconsin
Process
I applied through the university job postings and was contacted to do a coding test through Codility. They contacted me on a Tuesday, and I had until the EOD Saturday to complete the 2-hour test. They got back to me the next Monday to say they were moving on to other candidates. Codility tests are very math-focused, and many complain it doesn't accurately test your coding abilities.
Questions
Given an integer, if that int was represented in binary, how many bits would be set to '1'? (No time or space complexity requirements, only accuracy)
Give an integer N, find how many digits of 11^N are '1'. (O(n) space and time required)
Given a Tree with each node holding an integer, find the most unique numbers of any path on the tree. (Think it was O(n) space and time requirement)

- 3.0Quite good but not the very best employer in financeSoftware Engineer • Former EmployeeLondon, England, United KingdomNovember 6, 2023Pros: - Quite good salary (but not comparable with the very best firms on the market like Jane Street, etc.). - Nice people. - Nice and well-equipped office.Cons: - Very long hours (everyone expects you to look at the results, not at the time spent in the office, which basically means that people stay up to 12 hours in the office). - Bad salary and career progression. - Lack of transparency and clear communication between managers and workers (at least in my team).
- 5.0Great place – check with partner, thoughSoftware Engineer • Former EmployeeChicago, Illinois, United StatesFebruary 4, 2025Pros: Great place to work. Don sets the culture from the top in a very positive way. It is a meritocracy with little politics given the company's size.Cons: Front office jobs can have long hours. Speak with the partner you're going to work for. The company is big enough now that the different partners have different styles and personalities, and they are different enough you should know what you're getting into.
