ECI Telecom Senior Software Engineer interview questions

The company is in Bangalore but they had come to Gurgaon for hiring. My profile was screened and I was called for the interview. First, the interview asked about benefits of C++ over C, then he gave 2 DS questions. I wrote the code but he asked for the optimal solution. He also asked some questions on C++ concepts.

Tedious. Long face 2 face interview. With hiring manager and his managers and HR And I'm just padding my words here since I have to write at least 50 words I need to add at least 20 more words so I'm just writing more and more words. And some more words and more words.
