If you search for interview questions for DBAs, you'll find a wealth of questions. I also want you to be aware that, while the questions can be pretty good, some of the example answers such so bad that they have their own gravitational field. Use the questions as a study guide and then figure out the answers on your own if you don't know them right off the top of your head.
It's not exactly a DBA ONLY question but, one of my favorites it "Explain the differences and similarities between DELETE and TRUNCATE TABLE". It's amazing how many supposedly smart people (they're supposed to be because they're posting interview questions, right?) get it totally wrong. If someone got something that simple wrong, it would make for a very short interview.
If you look into "Geeks for Geeks", they offer interview "training". Again, consider it only to be practice and use it as a source of questions. IIRC, they have question for admins and developers in two separate tracks that do have a bit of an overlap.
My and, by default, your biggest problems with interviews is that the interviewers are frequently the same kind of balloon heads that are writing the questions on the internet and they're frequently just as wrong.
If you're going on a DBA interview, you DO need to be well versed in all the correct configurations for SQL Server and you need to know BACKUP and RESTORE by heart.
I can't give you any advice on any Cloud stuff because I don't work with the Cloud (hoping to retire before I have to).
About your 10 years of experience? Only you can know if if it will serve you in an interview or not. I've interviewed DBAs that have never done a native backup and I even interviewed one "expert" on performance tuning who, when I asked him about clustered indexes, told me he'd never worked with one. When I asked him "why not", he told be it's because he'd never worked on a clustered server before {head-desk}.
Say what you know and don't be afraid to say you don't know but explain what you would do to find out and give an example of how you've done that in the past.
And, remember... a DBA actually DOES need to know some SQL.

I have a magic phrase I've memorized and you can have it too.
"I don't know, but here's how I'd find the answer..."
Now, you have to have a plan for finding the answer, and it really, really, should be more than "google it". And honestly, that, how you'd find the answer, is to me, what separates someone with 10 years of experience from someone with 1 year of experience x 10. So, do you have that answer?
You know what you know. You don't know what you don't know. The only thing that's going to change that is learning, practice and experience. Of course then, youj start getting old and forgetting what you know. Ha!

It really is going to come down to what you know. You can memorize a bunch of interview answers, sure. And then they ask you something not on the list. What then? Or better still, they ask you an open-ended question. One of my favorites in an interview was this: You get a phone call. Someone is complaining that a database you're responsible for is running slow. What do you do?
Now, there's literally not a right answer here. We're going to explore your thought processes and understanding of SQL Server and how best to troubleshoot it. This is what I mean when I say it's all about your knowledge and skills, right now.
As for prepping for interviews, I do agree with this. I focus that prep on the organization I'm going to interview with. What do they do? How big are they? All this sort of stuff so when I go into the interview, sure, I'll answer their questions, but I'm going to have more than a few of my own. How big is the team? How do we integrate with development? Where are we with automating day-to-day operations? When was the last production outage and what was the cause? How did you deal with it? Interviews are a two-way street, and your focus should be on the stuff you literally don't know, the organization. If you've got 10 years of real experience in SQL Server, you should be able to answer most standard questions and then, when you hit something you don't know, you trot out my magic answer.

Hi jeff thanks for advice , i went by website you suggested geeks for geeks and i found it to more for programmers . .I didnt see anything related to DBA there hope i was on same site which you referring possible kindly dm me website link so i am sure i was on correct website .
I am what you call programmer dba so i know basics of sql but not good at that ..
once again thank you
Near the top center of the page, they have a search box. Search for "SQL" and that'll get you places.
Of course, this site also has some more "advanced" stuff in their selection of "Stairway" articles. There's a clickable link for STAIRWAYS at the top of this page.
Being mostly a "Programmer DBA" myself, let me ask... do you know what a "Tally or Numbers" table is and how to use it to replace all sorts of loops, cursors, and recursive CTEs that read one row at a time to do something with?

Understood. Be advised that I've found that even "pure" sys admin jobs require some knowledge of T-SQL.
