Technical screening is performed by... I am still not sure that the person doing it understands anything in IT. It looks like he has a list of questions and correct answers. Even if a question is open, you need to guess the right answer.

For example:

• What transaction locking do you prefer on money over a debit account, optimistic or pessimistic lock? It depends—what is the structure, how is the process organized? No, it is not: optimistic or pessimistic lock.
• Please list the Java classes you used for concurrency. I listed 5... Is that all? Nothing more?

And the whole interview goes in that kind of way.

List Java classes for concurrency.

For money transfer, would you prefer optimistic lock or pessimistic lock?
