Tip 1: In your first iteration of learning any topic, aim for 100% completion, not even 99%. Mastering it fully the first time makes subsequent revisions much easier and more effective, unlike covering only 80% and struggling later.
Tip 2: Participate in regular contests. They help you build consistency, improve speed, and sharpen your problem-solving instincts.
Tip 3: If you’re in your first year or early second year, start Competitive Programming as early as possible. The earlier you begin, the more time you’ll have to grow, practice, and excel.
Tip 1: Quantify every achievement - clearly state what you did and highlight its measurable impact.
Tip 2: Keep your resume concise - include only the most relevant details. Ensure you showcase at least two projects you’ve built independently.
The interview lasted for one and a half hours and was conducted over Google Meet.
The overall experience was good — the interviewer was supportive and made efforts to keep me calm, ensuring I didn’t feel pressured during the process.



You are given an m x n binary matrix grid.
A move consists of choosing any row or column and toggling each value in that row or column (i.e., changing all 0's to 1's, and all 1's to 0's).
Every row of the matrix is interpreted as a binary number, and the score of the matrix is the sum of these numbers.
Return the highest possible score after making any number of moves (including zero moves).
Step 1: For each row, if the first bit is 0, flip the row.
Step 2: For each column (from column 1 to n-1):
Count 1s in that column.
If number of 0s > 1s, flip the column.
Step 3: After processing, calculate the decimal value of each row and return their sum.



You are given an array prices where prices[i] is the price of a given stock on the ith day.
Find the maximum profit you can achieve. You may complete at most two transactions.
Hint 1: Break the problem into two parts
Think of each day as a possible split point.
You can:
Make the first transaction from day 0 to i
Make the second transaction from day i to end
So for each day i, compute:
Max profit for 1st transaction [0...i]
Max profit for 2nd transaction [i...n-1]
Then combine them.
Hint 2: Use Dynamic Programming
Use two passes:
Forward pass to calculate max profit for first transaction up to each day.
Backward pass to calculate max profit for second transaction from each day to the end.
The HR round mainly focused on assessing my personality, communication skills, and cultural fit for the company. The interviewer asked questions related to my background, strengths and weaknesses, career goals, teamwork experience, and how I handle challenges or conflicts.
They also evaluated my interest in the company, asked why I applied for the role, and discussed my availability, expected salary, and work location preferences.
The conversation was friendly and relaxed, aiming to understand whether I’d be a good fit in the company environment.
Tip 1:Start with Your Uniqueness. Link It to the Role. Connect your unique strengths to what the company or role demands. Add Evidence (Project, Experience, Result).
Tip 2: Choose a Real Challenge (Academic/Personal/Professional). Explain the Context Briefly. Describe Your Actions (What You Did).
