My partner thought I was being a bit excessive when I bought a high-quality external webcam last year when she was applying for work, but I'm pretty sure it helped her during job interviews. Or maybe it would be better to say prevented her laptop's webcam+mic from getting in the way of presenting herself.
I was fortunate that, at the beginning of the pandemic when such things were essentially unavailable, to have a high-end external Logitech webcam. I had bought it a few years earlier for a project that ended up not panning out.
I subsequently set up my DSLR as a webcam but, while it worked, it's more trouble than it's worth for most purposes. (I do use it for video sometimes but the webcam is just more foolproof for day-to-day conferencing use.)
I would also have gone for one of the Logitech C920 variations, like the other commenter, but at the time those were sold out due to the pandemic (also mirroring their remark of being lucky to already own one). So I ended up getting a Logitech Streamcam - which as far as I can tell just adds a hundred dollars to the price because it has a nicer looking design and can handle 60fps.
... now that I'm typing it out I guess she might have meant that deciding to go for a more expensive camera was unnecessary.
