Once you fall for System Design and Actual Software Engineering, you get bored learning or revising DSA.

Actually 80% of system design interview questions come from just 20% of topics? My guide will help you focus on what really matters.

How to deal with a 90-day notice period?

- Set your notice period to 15 days or less.
- Don't resign blindly.
- Start giving interviews for every call you get.
- Once you feel confident that you can crack interviews, then resign.
(Because with a 90-day notice, most of the time, except for some companies that consider you resign in uncertainty)
- Tell HR that your project is ending in 15-20 days, so you can exit early.
- Crack multiple offers. Because one offer might not wait, but the other one will.
- 90 days is not always fixed. Sometimes, you can reduce it by using a buyout or by utilizing your earned leave.
- You can also give a personal reason (like family situation or relocation), but say it politely and don’t spoil relationships.
- Offer a smooth handover, documentation, and knowledge transfer. Ensure a smooth exit from your current employer.
- Negotiate smartly: use your new offer as leverage, explore buyout options, and ask your new employer if they can reimburse. (MNCs often do)

Multiple offers + smart negotiation = 15–30 day exit (even if your contract says 90).

And while serving your notice period… use that time to prepare. Most rejections don’t happen in DSA; they happen in System Design.

DSA gets you shortlisted.

But it’s system design that gets you the offer, especially in 2025.

Here’s how you can start learning system design:

A few years back, I asked a senior engineer what truly sets apart juniors from seniors.
He smiled and said:
“Juniors write code that works. Seniors design systems that last.”

That hit me hard.
Because coding can get you started,
but system design is what takes you to the next level.

That’s exactly why I created my System Design Course, to help you cross that bridge faster, and with confidence.
