I applied online. I interviewed at Lutron Electronics in Mar 2015
Interview
The initial step is phone interview for about 45 mins. The interview was quite good. The interviewer tells you about the company and then asks you puzzle of 3 bulbs and 3 switches and determine which switch is for which bulb. Later, you are asked a simple java question to implement, where you are given the scenario.
Interview questions [1]
Question 1
- There are 2 adjacent rooms and one room has 3 bulbs and the other room has 3 switches. Given only one chance to go from one room to another, how will you determine which switch is for which bulb.
- Implement undo() method for a paint class. (it should revert previous changes each time you call the method)
