Frontend Interview Preparation

#faang #frontend #javascript #interview

Just started my interview preparation for MAANG companies. I am going through lots of blogs and articles to list down topics which are important for interview preparation.

Although this is my first post, I have never thought of writing any articles/blogs. But this will be a journey, where I can express my learnings. I have enrolled to some of Udemy courses to brush up my skills.

Udemy Courses -

Don't go for all courses at once, go for one or two, please checkout the sample video before enrolling to courses. These courses are not expensive as I have waited for price drop and single course cost me INR 500 only.

Please don't be impulsive, buy only if you have interest in it.

Here are some of my findings -
