Based on my personal experience, interviewing for senior roles in technology feels much more difficult than the interviews I did for a junior or mid level roles. Interviewing in general, is like a Venn diagram where your experience and the interviewer's experience are the circles and you need to find a way to ensure that the questions being asked end up in the intersection where you both know well enough to showcase your skills.

As the role one is applying for more gets more senior, the larger the circles on both sides become, and it sometimes ends up being too hard to get to that intersection in the short duration of an interview.

That being said, I would recommend to to start applying for jobs, since the interview experience itself would be helpful to understand where you might need to improve.
