If I wanted to get my opportunity to interview at Google or Amazon for SDE roles in the next 6-8 monthsโ€ฆ

Hereโ€™s exactly how Iโ€™d approach it (Iโ€™ve taught this to 100s of students and followed it myself to land interviews at 3+ FAANGs):

โ–บ Step 1: Learn to Code (from scratch, even if youโ€™re from non-CS background)

I helped my sister go from zero coding knowledge (she studied Biology and Electrical Engineering) to landing a job at Microsoft.

We started with:
- A simple programming language (C++, Java, Python โ€” pick one)
- FreeCodeCamp on YouTube for beginner-friendly lectures
- Key rule: Donโ€™t just watch. Code along with the video line by line.

Time required: 30โ€“40 days to get good with loops, conditions, syntax.

โ–บ Step 2: Start with DSA before jumping to development

Why?
- 90% of tech interviews in top companies focus on Data Structures & Algorithms
- Youโ€™ll need time to master it, so start early.

Start with:
- Arrays โ†’ Linked List โ†’ Stacks โ†’ Queues
- You can follow the DSA videos on my channel.
- Practice while learning is a must.

โ–บ Step 3: Follow a smart topic order

Once youโ€™re done with basics, follow this path:

1. Searching & Sorting
2. Recursion & Backtracking
3. Greedy
4. Sliding Window & Two Pointers
5. Trees & Graphs
6. Dynamic Programming
7. Tries, Heaps, and Union Find

Make revision notes as you go โ€” note down how you solved each question, what tricks worked, and how you optimized it.

โ–บ Step 4: Start giving contests (donโ€™t wait till youโ€™re โ€œreadyโ€)

Most students wait to โ€œfinish DSAโ€ before attempting contests.
Thatโ€™s a huge mistake.

Contests teach you:
- Time management under pressure
- Handling edge cases
- Thinking fast

Platforms: LeetCode Weekly/ Biweekly, Codeforces, AtCoder, etc.
And after every contest, do upsolving โ€” solve the questions you couldnโ€™t during the contest.

โ–บ Step 5: Revise smart

Create a โ€œRevision Sheetโ€ with 100 key problems youโ€™ve solved and want to reattempt.

Every 2-3 weeks, pick problems randomly and solve again without seeing solutions.

This trains your recall + improves your clarity.
