As someone who does a lot of interviewing at a big company, by the time the candidate is in a room (virtual or real) with me large amounts of vetting has been done by managers and recruiting. I really only look at the resume for context if I even do at all. I'm there to cover a specific technical competency and soft competency, and any other data I can get in 45 minutes + bio break, make feel comfortable, and them asking questions.

I rarely have time to look at code repos unless asked by the manager/recruiter.

You are also likely interviewing with the wrong people. Most large companies are looking for as many of the best devs they can find for generic opportunities. They have many many slots to fill.

If you are looking for something very specific then you need to find a recruiter who does placement as well. Amazon (where I work) has two major hiring processes, direct to team where they are usually looking for a specialty or generalist and take the first qualified candidate, and generalized hiring where you have to pass a standard interview but then you begin interviewing managers and finding a fit. The second may be better for you, but you still have to pass a bog standard interview.

There is of course the third way which is have a friend on the inside do the pre fit and selling.
