An engineer recently shared his remarkable journey from earning Rs 3.5 lakh per annum to Rs 35 lakh per annum in just three years, all without formal guidance. After completing his BTech, he began his career at a service-based company. His first significant career move was to a mid-sized product company, where he earned Rs 12 lakh per annum. During this transition, he focused on solving coding problems daily, which helped him develop consistency and communication skills crucial for interviews. After 14 months, he switched to a larger product company for Rs 22 lakh per annum. At this stage, he participated in weekly LeetCode contests to improve his problem-solving speed and decision-making abilities. Finally, he landed a position earning Rs 35 lakh per annum, where the interview process involved open-ended questions and system design discussions. He conducted mock interviews and prepared leadership stories to enhance his interview performance. His key habits included a daily coding practice streak and maintaining a pattern document to track algorithmic patterns, which he believes are more beneficial than merely counting solved problems.
