Epicor Software Software Engineer interview questions

Starts with Aptitude and 30 shortlisted will move to Technical and further based on performance u move to Managerial round and further shortlists move to the final round which is HR round where basics will asked about your interests, background and future you are aiming for after getting placed.

The first step was the online mcq test at the campus which was pretty decent in terms of difficulty. The next round was interview round which was hard, the interviewer asked "How to code an emulator" and "What code would you use to code emulator". Sadly this was where i fumbled and thus got eliminated.
