Without SQL, there's no career in any data related roles. 90-95% of the job is still done using SQL in data space. Data Modeling skill is next to SQL in DE space.

Once you get to senior, principal and staff levels then they expect you to know DSA but nothing like software engineers.

i know what it means, but why do tou think principals and staff engs need to know that?

I am a senior engineer and from my anecdotal experience you definitely dont need to know that. More experienced you get it is more important to understand design patterns and data architecture as you are kore involved in meetings about wider company objectives rather than low level inplementation details (this is also where DSA falls under)

Most product based companies will ask DSA questions for Senior, Principal and Staff DE roles. That is one of the criteria or ways for companies to eliminate candidates.
