It was a step-by-step process:

A recruiter reached out to me on LinkedIn. I shared my resume.

I received an email the next day asking for my availability for an interview. I gave five optional dates one month away, but rescheduled later.

I received another email after three days, confirming the date and time, along with the interview process information and preparation guidelines.

Technical Round: There was one engineer on the call, and the link to the code pad was already shared. We connected, and the interview took off in a minute.

You have some sticks with positive integer lengths. You can connect any two sticks of length x and y by paying a cost of x + y.

You perform this action until there is one stick remaining. Return the minimum cost of connecting all the given sticks into one stick.
