Coding Question : How will you find the column name if a column number is provided just like in an excel sheet.
For eg: Column 26 is "Z" and 28 is "AB". so given a number like 506 find the column name.
I gave him all the approaches and coded the solution. -

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 knowledege of the technlogies and architecture of your project . He asked me a lot of behavioural questions back to back ,it actually felt like a rapid fire round of Kofee 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 consitency to prepare and trust me if I can do it,anyone can do it.
All the best!
