    • GraphQL allows clients to request only the data they need, reducing over-fetching and under-fetching.

    • REST API follows a more rigid structure and is easier to understand for beginners.

Interview preparation tips for other job seekers - I have no advice for experience professional.

But, if you're a fresher, don't apply for his company unless you're ok with 3.5-4 LPA, have expertise in Competitive Programming and can solve any hard leetcode problem under 20minutes. They won't ask for your introduction, your projects or your interest. No matter what role you apply for, backend, frontend, fullstack, app development, you'll be judged based on some really hard twisted DSA.

The interviewer says, they really respect CP guys in their company and I'm yet to see even one CP guy in the company. The interview will be totally based on you passing the test cases. Doesn't matter what your logic was or how close you were. Unless you pass the test cases, you're no good..

You can apply and go through the rounds yourself, if you don't believe me. But tbh, I found it an utmost waste of time. I understand DSA is essential, but is really hard level DSA required.

I mean, I didn't apply for Google or microsoft, I just wanted a simple dev job where I can utilise my project making skills.

If I had to go with CP, obviously I would've applied on Google/Facebook/microsoft. For what I'd apply here for a pay of 3.5-4 LPA.

Verdict: I got the job offer for Pune, 4LPA. But, after talking to some employees of the company I realised the work pressure, and the overexpectations and the old Techstack they been rocking. So, I negotiated for a higher salary of 5-6 LPA which other candidates were getting. Apparantly, I've been told that I couldn't answer some DSA problems and hence they cannot offer me the same, and also they withdrawn my offer. I am fine with it, because after hearing the reviews of its own employees, I made up my mind of not joining it for that low compensation anyways. If the Techstack was better, there was a chance, but with their current Techstack, I don't think it'll help any fresher in their journey as a backend/full stack developer.
