I was found by an agent. First, there was phone technical interview, pretty basic: types of index, types of tables, types of indexes in Oracle. Then there was in person interview by hiring manager. I need to write couple sqls, not complicated, again was asked about type of joins and indexes. How would I tune a query, main steps, then by a second manager I was asked couple behavior questions: my strongest skills, about difficult situation, etc. Please keep in mind, CITCO has a policy: they pickup 3 persons, process all interviews with them, then decide is there anyone suitable or they'd like to pick up another 3 and so on.... That what can tell any recruiter, who is working with them.
