Interview Process
The interview involved a discussion about designing an expense system. The interviewer initially did not specify the requirement for group expenses, leading to follow-up questions. The candidate proposed using a rule abstract class or interface along with the strategy pattern for the evaluation method, but the interviewer found this approach too complex. The candidate then suggested storing rules in a hashmap and using a separate evaluation function, which the interviewer accepted as a simpler solution.
The candidate then created a Rule class with an evaluate method that could switch evaluation strategies based on input. The interviewer agreed with this approach. As time was running out, the candidate printed the output of the evaluation, which the interviewer confirmed was correct. With five minutes remaining, the candidate was encouraged to ask questions about the company, but due to time constraints, the interview ended before discussing group expenses.
