If I wanted to get my opportunity to interview at Google or Amazon for SDE roles in the next 6-8 monthsโฆ
Hereโs exactly how Iโd approach it (Iโve taught this to 100s of students and followed it myself to land interviews at 3+ FAANGs):
โบ Step 1: Learn to Code (from scratch, even if youโre 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: Donโt just watch. Code along with the video line by line.
Time required: 30โ40 days to get good with loops, conditions, syntax.
โบ Step 2: Start with DSA before jumping to development
Why?
- 90% of tech interviews in top companies focus on Data Structures & Algorithms
- Youโll 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.
โบ Step 3: Follow a smart topic order
Once youโre 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.
โบ Step 4: Start giving contests (donโt wait till youโre โreadyโ)
Most students wait to โfinish DSAโ before attempting contests.
Thatโs 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 couldnโt during the contest.
โบ Step 5: Revise smart
Create a โRevision Sheetโ with 100 key problems youโve 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.

Working under a bad tech lead can slow you down in your career, even if you are the most talented
Hereโs what you should do if you're stuck with a bad tech lead:
Ineffective Tech Lead:
- downplays the contributions of their team
- creates deadlines without talking to the team
- views team members as a tool to build and code
- doesnโt trust their team members to do their jobs
- gives no space or opportunities for personal / skill development
Effective Tech lead:
- sets a clear vision and direction
- communicates with the team & sets realistic goals
- empowers you to make decisions and take ownership
- inspires and helps you achieve your career milestones
- always looks to add value by sharing their knowledge and coaching
I've always grown the most when I've worked with the latter.
But I also have experience working with the former.
If you are in a team with a bad tech lead, itโs tough, I understand.
Hereโs what you can do:
โฅdonโt waste your energy worrying about them
โฅfocus on your growth and what you can do in the environment
โฅfocus and try to fill the gap your lead has created by their behaviors
โฅtalk to your manager and share how you're feeling rather than complain about the lead
โฅtry and understand why they are behaving the way they behave, whatโs important for them
And the most important:
Donโt get sucked into this behavior and become like one!
You will face both types of people in your career:
Some will teach you how to do things, and others will teach you how not to do things!
