Tricky test task for getting a job in a Germany company

[DimaKozhanovsky]

Below the description of the task.

You will see two charts. On the left you see the chart as it looks right after being inserted by the customer. This chart does not show any exclamation marks or warnings, as they are called in think-cell.

On the right side you see the chart after the customer edited it. As you can see, sometimes warnings are added and sometimes they are not, even though the label text was edited.

Can you provide your colleagues with an explanation for this behavior? Again, please provide us with a clearly structured account of the problem.

Include all (technical) information that is necessary to understand the problems or to further investigate them.

Include all sources (websites etc.) used.

Include the results of your own analysis instead of only referencing the information you found.

Take into consideration all relevant information given and point out which information is irrelevant for which problem and why.

Please try to infer from the attached example at least a total of three of the rules think-cell implicitly uses to decide when to add/not to add a warning.

Please provide your colleagues with a clearly structured presentation of these rules (as a text, as a table etc.) Please note that this presentation will be sent to the customer and should immediately make them understand the rules, so make sure to explain them very precisely.

Can you think of any arguments to why it would be advisable to have/not to have this feature?

Please present your thoughts on both problems in an email to your colleagues.

Please help me find the correct solution for this task. Thanks in advance 🙏
