I have read a lot of comments on here that leaving early is a very bad look for an intern. I, however, rarely get work to do. I have had some people (one being my mentor) tell me that facetime is not important and I should ask my team one last time if they need anything around 5:30 and they never do so I leave around 6:00. Is this going to affect me not getting a return offer? Also what are some things I should do to look busy during the day. I have been struggling to come up with new things to work on for hours on end.
