Interviewer: "Do you want this pocket calculator?"

I have mobile, no thank you. 😐😅

answer, sure, i always like free stuff.

I am unable to comprehend what does interviewer wants to know by this question!

@yendenikhil It happened after an interview that ran out of control. That guy needed a new software for his company and wanted to hire a dev for that, but he had no clue about software or programming. Finally I recommended him to try some standard software.
The calculator was a present for the consultation that he got for free...
