I'm an intern working at a software company. I have been here for a few months now, and my internship is coming to an end. My school requires feedback forms from people I have worked directly with during the time of my internship. These forms are quite extensive, and could take an hour to fill in (If not more). These feedback forms show the school how I have been doing during my internship, so they tackle subjects like 'Performance in Team' or 'The student works independent', just to give some examples.
I have worked with 2 people directly, the CEO of the company and the product owner of the team I was in. Recently, the product owner got assigned a new task, and is extremely busy. (Last day, he continued working until 11pm).
I have asked both if they wanted to fill in the form, and they both agreed. Today, I received the form from my CEO, but my product owner hasn't filled in anything yet. I assumed it was because he's very busy. When I asked him yesterday if he could fill it in tomorrow (Today) he apologized for being late, and promised to fill it in first thing tomorrow.
I haven't received anything at the time of writing this, and my deadline is coming up. It isn't a possibility to ask someone else, since they were the only 2 people I worked directly with. I also don't want to bother him too much, since he's already pretty stressed out.
What would be the best course of action to do? I don't want to annoy people here, but I do have that deadline coming up...
Edit: I forgot to mention the deadline for me handing in the report was supposed to be today. I have sent a mail to school asking if it's possible to hand it in later.
