question3

If you have to run an every minute recurring job (lots of checks and user processing here) for 
5000 users (and growing), explain in details how will you do it having in mind that each job 
may take between 4 to 7 minutes to executebut still has to be at one minute interval 
(there will always be parallel running jobs at any given instance).


ANSWER
The best way to make the RUN IS TO QUEUE THEM UP AND RUN Asynchronous
