Most difficult questions were related to SQL specifically. They want a senior PL/SQL developer and not just a basic SQL user as it was mentioned on job description. Nested queries, decoding SQL queries.

The ONLY difficult question was one of those brain teasers some companies like to use to see how candidates think on their feet. It was not one of the concise examples (i.e. "Why are manhole covers round?" or "how many tennis balls can you fit on a Boeing 757?") It was lengthy: Situation: There are 4 people on one side of a bridge. They must cross the bridge. It's nighttime, so they must use a flashlight. They must cross in pairs. One person can cross the bridge in 1 minute, another takes 2 minutes, another takes 5, and the last person takes 10 minutes to cross. When crossing, each pair will move at the pace of the slower walker. One person will have to make a return trip with the flashlight so the remaining people can use it to cross. Their walking pace also applies to these return trips. Question: In what sequence of pairs should they cross the bridge, such that the total time for ALL 4 to cross does not exceed 17 minutes. All other questions were standard personality gauging, behavioral, or experience-related questions, which is why I rate the overall interview process as average.
