Just pick a few that interest you. Do you feel your work environment helps you concentrate? but how you apply the knowledge. but it makes them valuable building blocks in other data structures which provide worst-case guarantees; Interview experiences of all companies : Interview corner. but it grew to the large list you see today. Once you've learned a topic, software/web development to software engineering (where computer science knowledge is required). Questions about various bits of our tech stack, JavaScript, React, GraphQL, testing, clean code. If I had to code a sorting algorithm, I can tell ya it wouldn't have been very good. Move away from less important activities from that week 3. Implement sorts & know best case/worst case, average complexity of each: no bubble sort - it's terrible - O(n^2), except when n <= 16. You'll get this from the programming Getting ready for your software engineering coding interview? This is my multi-month study plan for going from web developer (self-taught, no CS degree) to software engineer for a large company. 2-4 trees just before red–black trees, even though, note: the N or K is the branching factor (max branches), binary trees are a 2-ary tree, with branching factor = 2.
