There were 3 rounds of interview. First round covered almost all the basics that a frontend dev should know, HTML to CSS to JS to browser fundamentals - it was taken by Principal Software Engg. Second round was more focused on web page Optimisation, like image optimisation, using CDN etc Third round was with the Founder, basic behavioural/HR crap. I cleared all rounds, but later HR calls me up to discuss the offer - she offered me pretty much the same CTC I currently have. Later told me, she'll reach out once they have new project coming in because they want me as a "senior" dev. Never called again, lol.
