Hi,
could you let me know what you test with database here, so you can ask question here and i can reply out with my best knowledge.
Sorry the test, is actually a task.
Sure, ask me anything and i will google it.
But in all seriousness, the best way to tell is by giving them a small task, asking for previous work, or trying the applicant for one day while having a close look -- other than that you will waste your time.
It is a task, sorry for the confusion.
If seriously need to do, he can also get small work hired by other guy and get work done, so in fact, if really need to tell anything misleading, he can do by anyways.
That's assuming that OP is paying too much money for the guy to be able to split it between him (the mastermind deceiver) who will enjoy free money and instantly find a guy to outsource the work to.
You can't outsource this work. Our database has grown to levels that are really pushing the database to it's limits. We tried to hire a small consulting team, and they wouldn't even do the work, just due to the scale. I have been doing the work myself but I am getting too tied up with other stuff, and would like to pass it on to someone that can really know what they are doing.
