Mettl Software Developer interview questions

every thing from day 1 is just a waste of time in this company i gave my interview in this company , first it was a coding round , i cleared that , then there was my technical inteview scheduled, and my interview was good , i was selected for next round , now in the last round , By god , i have not given such a round in my entire experience , as i was pretty much sure that i have cleared that round. as i have given answers of all questions , and finally i got response as negative , now i will tell u the reason behind this , as there is a much more politics in this company , they prefer only reference guys and if they gets someone with lower package expectations , they prefer them so its just a waste of time , donot give interview in this kind of companies and finally , after calling HR many of times, that please tell me the reason why i was rejected , it has been now 2 months , they even donot have any reason also, worst experince of my life here remove politics prefer guys who has skills , and do not compare based on references and all At least tell someone the reason , why got rejected if u cannot give someone his expected salary , donot waste his time for the interview also
