Update: 80lpa in 2022 for 2/3+yoe Original (2019-20): I think for a 3 year experienced software engineer, video until 34:02 is more than enough for an interview. 1. Heap divisions and GC working 2. Types of GC and their commands Present a story revolved on the below topics on the day of interview and ask for 35LPA Rs. Get competing offers and negotiate to 45LPA Rs / 300K USD / 85K Euro / 100K Pound / 150K SGD (these are the maxed out TC ranges, only RSU/4yr included, per geography I have collected from TeamBlind, levelsfyi, reddit and LC ). Other important Java topics: 1. Oops 2. String, String Pool, Immutability, Builder, Buffer 3. Collections: When to use what, equals, hashcode, comparable, comparator, internal implementation of Arraylist and Hashmap 4. Generics: Why generics, type erasure, generic class and method 5. Thread: Race condition, synchronize/lock, threads block/Deadlock Less important Java topics: 1. Exceptions 2. Serialization 3. Reflection 4. Unit test 5. Design patterns: Atleast singleton Spring: 1. Why spring, spring boot 2. IOC and Dependency injection 3. AOP 4. Design and Implement an api: controller, service, repository, entity, model, mapper, validation, security, datasource config in yml, liquibase, unit test case DBMS: 1. JOIN 2. Normalization 3. Index 4. View Distributed systems: 1. Each component of Netflix OSS (or an alternate AWS resource) 2. Sql vs nosql 3. Monolith vs Microservices 4. Request response vs Event driven (Event notification, Event sourcing, CQRS) 5. 2pc, 3pc, SAGA Algorithms: (Leetcode, CTCI) Array: left scan, right scan, svan with storing computation, two pointer, sliding window String: sliding window, int char string conversions, int[26], int[128], int[10] LL, Stack, Queue, Monotic stack and queue, Deque: All classic Qs Heap: classic Qs Tree: classic Qs Graph: classic Qs DP: classic Qs System Design: Grokking and Primer

Your knowledge and understanding is incredible. I would be interested as to the path you took to arrive at where you are as a Jedi programmer. If you know of any great books and material that would guide the rest of us in a similar path, I would happily follow. I have watched several of your videos and I don't think I've seen a better teacher online. I absolutely love your videos and will definitely keep watching master Yoda.
