Benthon Labs Software Developer interview questions

This is a services based consultancy company. They conduct hiring for other companies. They interviewed me and then said that next round will be scheduled for the next week. They rescheduled this interview for about 4 times... and 40 days passed scheduling and postponing the interview, and then suddenly there is no reply... ghosted. What I find out, while they were delaying my interview with the client, in parallel they were arranging interviews for other candidates all along the month at a lower CTC. For 40 days they kept me hanging... panel is not available, can not be scheduled for today and blah blah... 5-6 candidates went by and they kept me waiting for a difference of 2LPA. And now they say the position is closed... we have kept your profile for next opportunity!!! Absolutely no respect for others time and efforts. There is no worth of their words.
