Data Structures and Algorithms

Algorithms that are typically seen for generalist software engineer roles

Frontend developers as with any other software engineer role should know basic data structures and algorithms. A high level understanding of basic computer science concepts is foundational to becoming a better engineer. However, it also helps with problem solving in any programming role.

It's not surprising there will be at times interview loops that involve traditional algorithms mainly to test whether a candidate has the basic foundations to solve problems algorithmically.

Typically sites like leetcode.com or hackerrank have been popular for practicing and finding solutions to common algorithm problems that may often be found asked by different tech companies.

Neetcode's site has a great breakdown of the different patterns that make up the common groups of algorithms that may be seen during software engineer interviews.

Generally what I've seen useful has been a focus on the following types of patterns/groups:

Commonly Seen	Least Commonly Seen
Arrays and Hashmaps	Graph
Two Pointers	Dynamic Programming
Sliding Window	Backtracking
Search/Sorting	Linked List
	Tree
