"The SQL interview FAQ is the single best resource I used. The worked answers explain the reasoning, not just the syntax. I cleared two rounds at an MNC within weeks."
"I came in as a mechanical engineer with no coding background. The C and Python tutorials took me from zero to a junior developer role in six months."
"The placement cell did more than send me job links — they reviewed my resume line by line, ran mock interviews, and referred me to their partner companies."
