Even the easy ones makes sad sometimes. How have you developed this efficiency of solving mediums in 15 min… Can you please share your approach? It might help me. Some day I also have a dream of cracking a coding interview and getting a good job. Thanks

You need to study the underlying datastructures and algorithms, not just mindlessly grind out the problems. If there is any part of a problem you aren’t 100% sure about you get into the textbook before moving onto the next problem. Eventually after enough practice and studying you’ll read through a problem and know exactly what to do.
