Is DSA even used in real work? Honest answers only

I'm 6 months into my first job and I haven't used a single algorithm or data structure concept that I grinded leetcode for. Most of my work is:

  • CRUD operations
  • API integrations
  • Fixing bugs
  • Writing tests

Was all that DSA prep just for clearing interviews? Do senior developers actually use these concepts in their daily work?

Genuinely asking, not trying to be edgy.

Yeah, honestly, most of the time in junior roles you'll focus on those basic tasks. DSA knowledge is like a foundation. It's not about daily use, but understanding deeper systems or when optimizing gets real. At senior levels or in specific roles like backend or systems programming, you might need it.
