Resident Engineer Interview Questions

3,456 resident engineer interview questions shared by candidates

Study up on your algorithms and data structures. Make sure you're comfortable with using common data structures and algorithms to solve more specific problems, but also be prepared to answer questions with no connection to any previously learned tricks. You should be able to come up with time complexities as easily as breathing. For everything you write, you have to be able to explain your thinking. In some cases, you will be asked to verbally articulate a complete solution before writing any code at all. In general, what they seem to be looking for is observable proof of your problem solving ability in real time. You don't need a freakishly high IQ or vast knowledge base of CS information to succeed, though I imagine that would help. To prepare, sites like leetcode seem to work fine, but in my opinion they put way to much emphasis on test cases and actually running code to be used for interview preparation. I often found that I would work a problem until I'd thought of the solution, then abandon it after a few minutes of trying to debug some edge case that wasn't working. This kind of behavior is obviously inappropriate on the job, but it helped me focus on the conceptual problem solving skills needed for the interviews.
