Tech Mahindra Senior Technical Associate interview questions

It started with a recruitment agency contacting me for a position in Tech Mahindra. I gave them the necessary details including the expected CTC. The person at the other end said she would need to check with the company if they would be willing to pay that much. After a couple of days a recruiter from Tech Mahindra directly got in touch, said they would like to take it forward and arranged a telephonic technical interview. Once I cleared this round, a managerial round was conducted which focused mostly on my previous experience (non-technical). After this, the TechM recruiter set up a Skype call which the HR manager never bothered to join. This happened twice and a week passed by. She then asked me to visit the TechM office in Powai, Mumbai for a voice verification round, for which I travelled halfway across the city only to find out that it involved a 2 minutes phone call with the manager. Once this was done, the usual forms were filled and documents collected as I waited for the recruiter to discuss the salary and joining dates. From this point onward, TechM kept postponing the discussion, giving excuses such as the CTC has not been approved yet. I had to constantly follow up with the recruiter to get an update on the process. This carried on for 3 more weeks after which the recruiter told me to expect a call from a Senior Project Manager. The call never came. When I asked about it over email, she finally told me that the CTC has not been approved and may never get approved. An entire month wasted for nothing over a company with highly unprofessional and unethical recruitment practices.
