TD Software Engineer I interview questions

Intro call into second follow up call into tech assessmentinto final round with manager level person. Talked discussing experiences and tech used in previous roles etc. Everything was relatively fast and smooth process.

I was assigned to speak with 2 engineers from the company. They asked me about some of my previous work experience and my learnings from those. From there, they asked me the interview question below, followed by giving me time to ask any questions I had.
