Deutsche Telekom interview questions

Interview Process was simple and quick which involved following rounds. Process completed in a day and response was immediately given. Overall experience was good. Difficulty level was average. 1.Aptitude test 2.Technical round 3.HR round

First round coding test, second round technical discussion, third round technical discussion. All 3 rounds scheduled on 3 different days. I cleared all of them and later they asked to submit documents. Submitted documents but no further updates for a week. I called HR but they ignored my calls. Later I tried from different number and got to know that their budget is not matching with my expectations. If this is the case they should not schedule my interview as I have already shared my expectations in advance with consultancy and company HR. This is bit unprofessional experience.
