The most difficult question was regarding a DC motor. 'what will happen if we remove the magnetic field?' I answered that since there will be no field, there won't be any torque generated and hence the motor would not work.

I believe what would happen is that you would burn out the stator of the DC motor. It happens because there is no resistance from the field and the stator wiring has infinite current which causes it to burn up. Less

Why do you think university graduates often lack the skills to perform in industry?

2 Answers

In my opinion : 1. It depends on what is your measurement criteria of performance. Technical? Project delivery? Attitude? How long is the period of your measurement of the performance? 2. As expected, a freshie require guidance from senior Engineer. If it doesnt perform, means the leader/senior engineer doesnt guide well. 3. Some freshies got the job differs from their qualification and field of study. Therefore they require ample time to build up the knowledge and experience to adapt in the industry. 4. If your measurement stick is meant for 10 years experience engineer but you were applying for freshies, it doesnt add up definitely. Every engineer has their own KPI right? Less
