How would you verify if a candidate know how to use a database engine? This can actually have a lot of depth
- jiggawatts 1y agoI simply ask the candidate what a B-Tree is and how a database engine would use one. If they don’t know that, then the database engine internals will forever remain a mysterious black box to them. Explaining each of the four letters in ACID is the follow-up question if they pass. These are the equivalent of “why do we put steel rebar into concrete?” If you can’t answer these questions immediately upon graduating then you cannot ever be responsible for anything. You can only be entrusted to copy or “fill in the blanks” where an anctual engineer worked out the design.
