Hours are flexible, but as a graduate, my hours are quite long in order to learn and understand tasks in order to deliver them to an adequate standard.
Very flexible however I (and everyone else in the office) tend to spend way longer than the required hours in the office.
NDY is quite flexible with hours as long as the work you are assigned is completed. Start and end times depend very much upon getting tasks done in time for a project to be delivered with outstanding quality.
