Possible Answer #1:
“I could not secure a perfect 100/100 in my Math paper in 12th Standard, despite my hard work.

That is my greatest failure till date.”

Possible Answer #2:
“Last year, we wanted to improve sales by 50% but achieved just 35% which was a huge letdown, even if there was a huge boost to our ROI.

The underlying issue was that I was on a holiday and my entire team took this last big deal for granted.

They are all star performers, but I don’t know why they took this sure shot deal so lightly.

We had built a great rapport with this client over a period of 3 months and the deal had almost been wrapped up.

That was a huge failure in the recent past for me.

Eventually, the deal slipped out of our hands and impacted the overall sales percentage.”
