OPNET Java Developer interview questions

The process consisted of screening, coding problem and a code review after a screening by senior developer, the recruiter gave a fixed a one hour time frame and gave a coding problem. It was a simple OO problem of queueing the Aircrafts based on priority. Next. the code review: questions on the running time for the algorithm. Clean and more generalization is expected from the code. I havnt heard from the recruiter after the review.
