Xylem Software Engineer interview: fundamentals under pressure

The interview was hard and highly conceptual. I had to think deeply instead of reciting facts, and vague answers were not enough. They wanted precise answers grounded in fundamentals.

I do not remember a long, step-by-step sequence of stages. What I do remember is that the difficulty stayed consistent: conceptual depth mattered more than quick problem-solving tricks.

I did not receive an offer. Looking back, the gap between what I knew and what they tested for was what decided the outcome.

Location: Chennai. Overall feedback: neutral. Offer status: no offer.
