One problem that I faced even after solving 500+ questions during my preparation time was: before interviews, which questions to choose for revision, after all, there are just so many questions for me to choose from, right?

I faced this problem for a long time unless I did some research on the best-curated lists that consist of the most common questions asked in interviews. Here are 35 questions which will help you to revise your concepts before an interview👇🏻

The easiest way to learn all of these skills is by connecting with experienced SDEs from the start

I screwed up 3 interviews because I didn’t solve my Low-Level Design (LLD) problems properly.

Here is a complete roadmap for learning Low-Level Design (LLD):

DSA alone won’t save your job.
FAANG-level interviews now demand:
🔻 LLD & HLD
🔻 System Design
🔻 Real-World Backend Skills

Keep ignoring this, and you’ll be stuck in service companies while juniors get ₹45L+ offers.
