My github account was brought up in a recent technical interview. The hiring manager felt that my account lacked professionalism because I had several >= 1 year old, unfinished repositories.
That is... bizarre. He should look at the abandoned internal repos of the average software company's experiments and realign his expectations with reality.
I think that was their thought process. My personal Github is a bit of a graveyard/dumping ground but I saw this as a wakeup call and got rid of a bunch of forked repos and combined some unfinished projects into other repos.
