Of course I have no idea how you present yourself or how things exactly are at your location on earth, but they could feel you're overqualified. If you have tech jobs on your resume they could easily assume they can't pay you and/or you get bored at the job and leave quite quickly.
In my experience the best way to get in somewhere is to build a personal connection. Try to reach out by phone or in person to the other side. Make sure you understand the person and the company on the other side. That really helps to get to the top of the list, especially at smaller companies. Then still it can take a thousand no's to get one yes.
Pretty nice! Very useful idea, especially for videos on my watchlist I never get to because I feel they're too long.
Would love if I could ask follow up questions. Would be awesome to ask "Is X also explained?" and get a little summary back with the timestamp so I can jump to that point in the video.
Also it feels a bit slow and doesn't really give feedback whether it's making progress. That would be a good UX improvement.

Good luck! Hope you land a job soon!
