Assertion Automation Engineer interview questions

Interview process of any company is a reflection of their values! In my case i had a very bad experience. I had 3 rounds of interview, in the second round they gave me a coding question related to automating the API which more or less looked like their internal project. I provided them with a working code post which they scheduled my further rounds. After waiting for two weeks and constant follow ups with HR i was informed that they dont have the budget to hire and are going forward with an internal employee. I spent two complete days to complete their coding assignment. Looks like they only needed a working code for the project and not an employee.
