My son applied for an engineering PI in mid February (when they first came out). The job did not close until March 31. I know that no activity usually happens until after that closing date, but just concerned that he's just "in submission", not "in progress". He seems kinda "stuck". Is this typical? I know that engineering does things differently from other PIs, but this is his third time applying, and he's never been in submission this long. Previously he was in progress for a couple of months til he went NLIC. Any input is greatly appreciated. Thx!
