I am currently interning at a small company, so I answer directly to the CEO himself. I started at the beginning of the year and the role was said to be for a few months at least, though we did not discuss formally how long it would be. I did specify at the outset that I would be later looking for a permanent graduate role and this was acknowledged.
Now, in the coming weeks I have some interviews coming up during work hours, so will need to ask for a few hours off on someday, maybe multiple times a week. I am wondering whether I need to advise my boss that I am going to interviews? Because I am still getting a steady flow I presume they are under the assumption that I will remain for a while. My question is do I need to tell my boss I am going for several interviews in the coming weeks?
Edit: I would say my relationship with my boss is fine, but pretty much purely formal. We rarely have off-topic conversations, majority of interactions are work focused.
