Recently gave Flipkart SDE1 interview (3 rounds)

Going in, I was actually feeling ready this time.
Not like I will crack it easily, but at least not blank like before.

After each round I had that feeling okay, this was not bad

But yeah… result didn’t match that feeling

R1:
Array problem

I started with sliding window and explained it properly.
It worked for normal cases.

Then interviewer asked to modify it so that:

• duplicates are allowed
• but you still need to maintain some constraint on order

That’s where it got messy for me

My earlier logic was breaking for a few edge cases
and I had to rework part of the approach while explaining

I reached somewhere close, but I wasn’t fully clean with it
and I could feel that

R2:
This round was more draining than difficult

Problem itself was manageable

But after giving one solution, it didn’t end there
they kept pushing:

• can you reduce space here?
• what if input becomes very large?
• how will this behave in worst case?

At one point I had a working solution
but they were more interested in how I improve it

Felt like they were testing thinking depth, not correctness

R3:
Project discussion

This looked easy initially but turned out to be the toughest

They went deep into decisions I had taken months back

Questions like:

• why exactly this approach?
• what if traffic increases 10x?
• where will your system fail first?

Some answers I knew clearly
but few I had to think on the spot

and I wasn’t fully confident there

Final

Rejected

This one hit a bit more than usual

Because I didn’t feel lost in the interview
still… not enough
