Advice to all the Front-end engineers: I'd say it's best to stick to your strengths and focus on roles that align with your profile rather than taking up a general dev role(SDE) if you're really interested in Front-end or Full-stack maybe. The interview questions for Front-end positions I have interviewed for were mostly specific to JS fundamentals and ReactJS.
Preparation: For Frontend positions, the questions in interviews can come up from any of the following fields: JavaScript basics, DOM Manipulation, ReactJS, Data structures & Algorithms, JavaScript OOP's/Design Patterns and System Design.
