Made it to Amazon. Consistent practice is key.

I recently started working at Amazon as an L4 SDE. One needs to have patience and maintain consistency in solving the problems to crack the interview. My leetcode journey started when I started watching Striver's videos on Dynamic Programming because of algorithms class at University. I also got some understanding of some of the problem-solving techniques but then what drastically helped was joining cohort based classes named {S30} where we consistently discussed 2 Leetcode problems everyday covering majority of the problem-solving techniques. Another thing that helped me in this was the mock interviews they conducted so that you get an idea about how interviews are conducted. The cohort spanned 4 months but then after that it was self-study, understanding, and consistency.
