ABB PATTERN & INTERVIEW - 08 JUL 2016 - COIMBATORE
Hi Friends
I attended ABB last week and the test pattern is as follows:
1) Verbal section - 20 (20 mins): Very easy. No need special preps
2) Analytical - 20 (25 mins): Somewhat tough. Time matters
3) Attention to detail - 15 (15 mins): Easy. Questions like which two are
alike
4) Technical - 60 (60 mins): Very tough. Questions from almost every nook
and corner of EEE. More questions from switchgears, circuit breakers. etc
The test will be online and there is sectional cut-off. The shortlisted will
be called to Bangalore.
Interview:
More of technical. Be thorough with ur basics like the current eqn in series
RLC circuit. Questions may be from anywhere. Prepare ur project and paper
well. They asked abt the paper for one hr. Very tricky hr questions will be
asked. If u clear this round there will be a psychometric test and hr round
again. Not like all other companis.
U should be very formal and prepare well.
