After 2 days I got a call for the Hiring manager round which totally focussed on my work ex and projects. Be prepared with the in-depth knowledge of the technologies and architecture of your project . He asked me a lot of behavioral questions back to back ,it actually felt like a rapid fire round of Koffee with Karan :)
All the rounds were pretty good for me as I was well prepared on both coding and design side.
At one point , I became so rusty and almost forgot about solving DSA questions. It took me a while and a lot of consistency to prepare and trust me if I can do it,anyone can do it.
All the best!
