Test Ideas to test any Object?
Many times we hear that in interviews, questions like 'test a pen', 'test cases for a chair' are asked. What should be the best approach to answer these questions?
First off, best approach is to let them talk as much as possible and get clues to what they're looking for. There is no right answer to these type of questions except for the one the interviewer is looking for.
* Ask Clarifying Questions
* Don't assume, put it on them to describe their ideal pen, chair, etc... Keep talking until it is absolutely crystal clear you both have the same thing in mind down to the finish of the paint, the number of screws inside, etc...
2nd, they're looking to get a sense of your thought process. How far into the corners of the box you reach and how far out of the box you reach without looking silly.
* Go over the requirements with the interviewer. Walk them through what is expected of that object.
* Then start probing more into what those requirements imply.
- Are there any laws that apply?
- What regulations apply? (Does that Number 2 pencil have the right size lead?)
- What standards are implicitly implied? (ex: We expect a pen not to have lead based paint incase some baby puts it in his mouth)
3rd, Beyond simple requirements, think of what would make that thing stand out against competitors.
* Think of things that if it were missing, would make the product experience less enjoyable vs. competitors
- Is the Chair sturdy and reliable?
- Does the pen write with consistent darkness?
