Technical : They ask mostly from machines even if you say that your favourite subject is Power System They started off with transformer . Asked about vector groups and said me to draw Phasor diagram for Dy11 connection. I couldn't :| They asked the conditions of parallel transformer. I answered and another question followed What would happen if PU impedance of transformer are not equal ? I answered this too and that's it Endnof the interview . Rejected. They didn't even bother to apprise us of the rejection and made us wait for 4 hours. We all thought HRs being conducted for every branch.
