I think all of us have some sort of imposter syndrome to an extent, but the thing that helped me start to get over it was to just really talk to and learn from those same colleagues. You're the most junior on that team, so it's to be expected that you might have questions and have a bit more to learn, and what better way than to learn that from them directly. I think you'll also find that even they might have a level of imposter syndrome themselves and they just find ways to work around it. Something I've learned is that even the highest level people with all this crazy experience still started somewhere and honestly, you might find that some of them don't even have the skillsets that you have.
