Infosys Specialist Programmer interview questions

Rude straight away started interview without intro wanted to reject me without gap he was asking questions while i tried to explain he interrupted me way too many times seems unsatisfied.

after clearing online oa the onsite interview was conducted at Indore office there are two rounds at final onsite day first one in coding assesment those who have cleared any one questions out of two dsa ques they will move to the next step that is 1:1 interview also if you are not able to solve any of the question the will take your interview but deep inside we all knows that Coding round is the only deciding factor there interview was just a formallity
