*Nervous student comes in for the first interview I am conducting as a developer*

Me (as an interviewer): What is best approach to search data?

Student: It will take linear time but if data is sorted, we can do it in logarithmic time.

Me: [Smiles] Take a hint Hash Map?

Student: Yes, with it, we can do it in constant time.

Me: Okay, Bloom Filter anytime?

Student: *sweating* noooo...

Me: Okay. I am a developer so I know this.

Student: *about to cry*

Me: No problem but why will you search data when there is no problem? Don't you have better work.

Student: *confused* yup

Me: *laughs but immediately controls* Take it lightly. You know what you need to do this job. You are HIRED. :)
