I basically followed this path successfully to a FAANG company. https://medium.com/educative/3-month-coding-interview-bootcamp-904422926ce8 the courses on educative are great and recommended.

The other key thing I did was practice mock interviewing. Actually doing it and getting feedback is much better than convincing your self you know it by studying the same material repeatedly. https://iio.sh/r/Z1WA

If you have an ok grasp of the material relative to your target level then practice and even the interviewing.io coaching is the single best thing you can do.

will try to follow it and thanks
