Example: describe a challenges you faced during your last project

I think, the most important problem is 
misunderstanding and the lack of communication 
in the business life. If we come 
together as a group and discuss it, 
there is nothing we cannot solve. 
I'm really grateful and blessed to 
work with my current team because 
we are able to collaborate and come 
together to solve the problem

1-Last minute requirement change?
1. Last Minute Requirement Changes
It is quite common to change project 
requirements mid-sprint in agile 
development projects. Testers might 
have to redo the entire scope of testing 
since even the smallest changes to a codebase 
needs to be run through multiple tests to ensure 
its stability and compatibility with existing code.
For example, if a browser introduces an update, 
testers will have to perform browser compatibility 
testing to ensure that the website’s existing 
features run flawlessly even after the update. 
On the other hand, if a new feature is added to 
the website last-minute, cross browser testing is 
necessary to ensure that the feature works perfectly 
across multiple browsers.
It is possible that a feature needs to be changed or 
modified due to some changes in user feedback or 
software updates. For example, a feature might have 
to be modified because of a recent browser update. 
If requirement changes come through towards 
the end of a sprint, testers can prefer for 
running as many tests as possible within the 
time available. For this reason Tester should 
be very clear about the priority of the test aspects. 
For sure we cannot test all aspects of the updated 
feature in last minute, so we should have a 
good coordination with PO and developer to 
understand their approaches. I use 20-80 ratio 
for that purpose. The first %20 of the test cases 
should cover %80 of the features.
