5. Facts of Tech Interview • It’s never been easy (Well, you don’t say). • Don’t know what position you are looking for. • Pre-online test? Oh God why... • Confused of what to learn and prepare. • FAANG is my goal! • Impostor syndrome. • And the list continues...
6. Struggling? Me too! • Rejected in Google, FB, TikTok, Grab, Shopee, etc • Take note after each interview • Continuous learning
7. Position in Current Tech Industry • Most of fresh grads or intern are jack of all trades. • You have to be a T-shaped person. • Technical: ◦ Software Engineer ◦ System Engineer ◦ Data Analyst ◦ Data Scientist ◦ UI/UX Designer ◦ . . . • Semi-Technical: ◦ Product Manager ◦ SCRUM Master ◦ . . .
8. Online Test • My personal recommended tool: AlgoExpert • It covers both Algorithm and System design questions • Other free tools: Codility, HackerRank, Leetcode, etc • Cracking the Coding Interview by Gayle in Youtube • Solve 2-4 questions a week • Don’t be lazy! This will be useful for your whiteboard interview later!
9. Preparation • Resume: ◦ Not too long ◦ Show your interest ◦ Show your skills (Tech & Soft) ◦ What did you do? (Not your team) • Two types of tech interview: ◦ Whiteboard ◦ Domain expert (Optional). Usually after the whiteboard interview. • CS knowledge is essential for both types: ◦ Algorithm: Sorting and Searching. ◦ Data Structures: Trees, Tries, Stack, Queue, Linked List, Heaps, and HashMap. ◦ Advanced Topics: Recursion, Memoization, and Dynamic Programming. ◦ Space & Time complexity
