TP Customee Service Representative interview questions

They've put me through 2 phases of interview, first a phone call, then a virtual meeting, In the Job description they said the salary is up to 15000, and in the first interview they've made it very clear that it won't go less than 10000, suddenly after finishing the 2nd phase of the interview they revealed that I'm only getting 6000 ? why would you put me through 2 phases of interview just based on a lie ? 6000 really ? You should've made it obvious that I will do all of that for 6000, Then I would choose to not do it from the beginning ! You waste people time and make them feel low and weak for nothing, worst company I've ever dealt with, bunch of liars and fake people.

good for newbies common interview questions from hiring team/ recruiter from initial interview about basic infos, your expected salary etc. next was assessment typing test and simple logic test and then final interview.
