So I am at the client's location for onsite consultation of their projects.
The HoD asked me to create an application to accept feedbacks from multiple points urgently. Although I was there just for consulting, I thought why not, I am anyway getting bored here.
So after explaining the functionality, she asked me, when can she accept a working app. I told her that it would depend upon a lot of factors, so give me till evening to figure it out.
When she insisted I told her, that it can take at least a month with all the APIs, logins, UI, QA etc. She was surprised and told me that she expected it in 4 days since the requirements can be fit into a single page of her notebook. (That's how she measures project duration).

I told her it's impossible, given that I am the only one working on it. So she told me that her team can do it in two days. I probably have more experience than her entire team combined, but still I thought they might know some simple magic or faster way, that I might not, so I asked her to discuss with the team and then decide.

After explaining the requirements, when she mentioned that it should be done in 2 days, everyone was kinda frozen. One of them said that it's going to take at least 4 months.

I couldn't hide my smirk 😉
