Sollicitatievragen bij BondIT (Israel)

In the home assignment, Write a very nice AirportFlightScheduler with REST API. Afterwards, in the face-to-face interview you need to run it. I expected to be asked more questions about the assignment, but the interviewer switched to design questions very fast. One of the design questions was what should I do in case I have a DB and a server, and the server need to get a result from the DB, but there is a timeout of X seconds. The answer was to use WebSockets (I didn't know that).
