I interviewed with multiple teams in NY and each interview was distinct depending on the team/hiring manager. These are some of the questions I got asked:
How to delete a node in linked list?
What is a prototype in Javascript?
How do you implement a LRU cache?
What is the difference between a microservice vs monothilic application?
What is CORS?
What's the difference between a cookie, session, local storage?
How to check for balanced brackets?
What's the difference between a fat arrow vs normal function?
What is inheritance in Java?
What's a pom.xml file in Java?
If you are applying to backend/Java focused positions, make sure you study the OOP concepts (Inheritance, Polymorphism, Abstraction, Interface), Spring/Spring boot and microservices if you had prior experience.
If you are applying to Fullstack/Frontend positions, make sure you understand the Javascript fundamentals (arrow functions, ES6/ES7, JSON objects, promises/async await, CSS styling, CORS, React/Redux).
Good luck!
