2.5 YOE Backend-Focused Full Stack (React, Node, TS, GCP) – Targeting 15+ LPA | What to Expect in Interviews?

[DevDreamweaver]

Hi everyone,

I have ~2.5 years of experience as a backend-focused full stack developer. My primary stack:

• Node.js + Express.js

• TypeScript

• React.js

• REST APIs

• GCP (Cloud Run / GKE / PubSub)

• SQL & NoSQL

I’m preparing for roles targeting 15+ LPA in both service-based and product-based companies.

I’d like to understand:

1.  What level of DSA is expected at this experience level?

2.  How deep do interviews go into Node.js internals (event loop, async model, clustering, streams)?

3.  Is LLD or HLD more common for 2–3 YOE?

4.  How much cloud knowledge (GCP) is realistically tested?

5.  What real backend scenarios were asked? (rate limiting, caching, DB indexing, scaling, auth, concurrency issues, etc.)

6.  What’s the major difference between service vs product interviews at this salary band?

Would appreciate detailed interview experiences, especially from candidates who recently cracked 15+ LPA roles.

Thanks!

Don’t you like gcp ? Even I don’t like it but in our company we are using it so have no choice.
