Currently in a project, where for strategic and unrelated reasons, we ended up with 4 new juniors and had to hand off one senior. In a team that consisted of merely 3 people before.

So, it's just me and another guy having to constantly juggle these juniors to push them back into the right direction and review whatever code they ended up with.
It's so frustrating, because while I'll gladly pass on my knowledge, the project has basically ground to a halt.

There's so many tasks me and the other senior would like to just quickly tackle. Which should just take a few days, no big deal. Oh no, I rarely get a day's worth of work done in two weeks. The rest is just looking after the juniors, who cannot tackle many of the actual crucial tasks.

And it's not even like the juniors are doing a bad job. Frankly, they're doing amazingly for how little support we can give them. But that doesn't stop the project from falling apart.
