Aptitude test:- It was consisting 1 marks - 20 questions

2 marks - 15 questions

5 marks - 10 questions

1 marks had complete the series kind of quitions.

2 marks question were really tough rather time consuming. It was based on
time & work, train, water stream and age problem.

5 marks question were logical totally on C-language. Flow chart & programs
were given and was asked to find output, again was time consuming.

**Suggestions:**- Start solving 5 marks first.Can refer R.S.
Agrawal but more than that Self Practice is must. Questions were easy but
time consuming so practice for short cuts & better guessing power will
also help.

**English test:**-

It was really easy. Fill in the blanks & 4 options were given. I
think no special practice is required for this.

Only 32 out of 680 cleared it.

Technical Interview:- It was really brain teasing. You must be very clear
about your basics. Also u must have good command over C-language. Average time
taken was around 45 minutes each candidate.

or C++? Construction & explanation of JFET, CMOS, MOSFET etc ? all basics?.

Some candidate told to write different C-programs. Some were told to draw
Electronic Ckt diagram. Some logical questions also.

Suggestions:- Nothing will help?.. no luck factor ?only study hard
?be aware of your basics & some concrete C.

Only 13 out of 32 selected for HR round.

**HR interview**:- It was really a nightmare. 3 people were
interviewing around 45 minutes each candidate. Questions were like?tell me
