+
+#### Topics I got in interviews (JS)
+* Front-end optimization (check my blog)
+* Polyfill for:
+    *   Debounce (Akshay's video)
+    *   Throttle (Akshay's video)
+    *   Reduce (MDN)
+* PROMISES & CALLBACKS (VIP)
+* undefined vs null 
+* call, apply. bind
+* "this", arrow function
+*  strict mode
+* dom modification with js
+* event bubbling and capturing
+* currying
+* inheritance using functions (check my blog)
+* Garbage collector (Good To Know)
+* cookie vs local storage vs session storage
+
+#### Topics I got in interviews (REACT)
+* Hooks (what & why)
+* Lifecycle
+* Redux (basic)
+* "Key" in rendering.
+* functional vs class comp
+
+
+#### Code and system design (JS)
+* Implement "CSS sticky property with js" (I was allowed to google syntax :Sigh:)
+* carousel
+* Accordion
+* A decent UI from mock-up, API call, and all stuff (limited time)
+* lazy loading (surprisingly, smh I remembered the complete interaction observer boilerplate code.) :-)
+
+#### Code and system design (React)
+
+* nested comment, something like Reddit (1.5 hrs) where a user can click on any comment and reply to it.
+    *  At that time it was hard for me, I was able to lay down the complete logic showing and did UI for replying to comments but in end, it was ~80%. However, I got through the round :)
+*   Card shuffle, need to create a UI where on click: a deck of the card will be shuffled into 4 sets. It includes card shuffle and some logic that I am not able to recollect.
+    * FAILED, I found it difficult to code react in codepen (VS CODE made me dumb :P) and I was not able to collect my thoughts, may due to pressure (This was a BIG NAME) ¯\\_(ツ)_/¯    
+* File tree, something like VS CODE file tree where you click on a folder and it will show (and hide) inner files.
+* Design a Hackernews like of UI, explain state management.
+
+
+#### DS-ALGO
+> YES I FACED DS-ALGO QUES IN HALF OF THE COMPANIES.
+
+I prefer Leetcode for general interview prep.
