Well, I need to interview candidates because I need to know if they are up for the job when systems breaks. If a table query fails because it needs a btree index due to range searches, I want the candidate to know how a btree index works and why it fixes the issue. Also If somebody cant tell me the difference between http udp and tcp, its a no hire for me.
So for me, I really want to interview somebody before he can work with me.
