Yeah, we had a hard bottleneck for seniors, so they kind of got told to walk on their own as much as they can, but after just two weeks or so, I had to push hard against that, because they would frequently walk into wrong directions and then rectifying that would cost me significantly more time. At one point, I had to review a story three times, because they misunderstood the goal twice.

Similarly, we had a student, who would run off doing things for two weeks, and then suddenly she’d come up to you and tell you that she did this and this and that and now she’s stuck.
And then if the second ‘this’ was an incorrect decision, you have to sit down with her in that exact moment and redo a lot of her work to get everything back on track.

So, yeah, juniors who know when to ask questions are extremely helpful. Otherwise I have to poll them for questions, which takes up time, too.
