I am Akash Singh, a BTech Graduate working as an SDE-1 (Software Development Engineer-1). I prepare people for interviews by covering everything right from Aptitude to Coding Interview to HR Round. I usually follow a structured pattern while teaching. Eg. for solving sliding window problems, one should practice just 3 problems in fixed-sized window and 3 in variable-sized and I guarantee you that you can solve any problem that uses this technique. There is also a pattern to solve DP problems. I can easily make people understand the concept behind coding that can land you in a good reputed company.
