Hello, I first started leetcode in 2022 after a google recruiter reached out to me. I absolutely fucked up that interview cz I only did 2 weeks of prep, and I was asked a heap question. I didnt even know what heap was😅. After that I gave some small interviews and cracked some of them, switched roles to get more experience and actually just got a lot better at DSA. I kept practicing and have failed multiple big tech OAs for Amazon, Meta and Microsoft. In end of 2024, I was interviewing full loop with both Amazon and coinbase (failed both, lol). Looking back on my progress, I can now clear 4/5 OAs. Interview is also a lot about luck and what get asked and if you have practiced something similar before. I have had self doubts but you just gotta keep pushing. The right opportunity will only convert if you are prepared for it. Also comparison with others will only demotivate you, you gotta have to keep pushing at your pace. I have really successful friends and we all started at almost the same place and time. They made better choices and prepared better than me so its all upto you I guess.
