So be tough and ask a lot of technical questions during the interview. What to ask depends on what you are looking for, but here are the basics:

Ask standard computer science questions: data structures and algorithms. (If the person does not know what a Hashtable is or how it works or how to write one - thats a big red flag)
Get a feel for knowledge of the language: It does not matter what language they claim fluency in - confirm it by asking specific questions
Senior people need to know threads, queuing, distributed systems, databases
Senior people need to know design patterns
Senior people need to know unit testing inside out
Most importantly, the candidates need to demonstrate love for simple and elegant code

How dod I find out how much electricity something uses

How do I find out how much electricity something uses?

Later on we'll cover how to measure the exact amount of electricity something uses. But the shortcut is to just look at the label! Nearly everything you can plug into the wall has a label that says how much electricity it uses. (It may be printed directly into the plastic or metal.) You may have to hunt for the label. It's often located on the bottom or side of the device, or possibly where the power cord enters the unit. If the device is powered with an AC/DC adapter, the electrical rating is usually listed on the adapter itself.

Watt VS voltage Amp

clipper's remarks: The question was need to replace an adapter for my stepdaughter's notebook. Her old adapter (her dog chewed the cord) is 16 volts. I want to buy her one through Dell. Dell has adapters that are in watts. Are they compatable? How do you convert one to the other?

Wattage is the amount of power used. It is the voltage multiplied by the current (in amps). You can't convert from the Dell specification of watts to the old one in volts.

A DC power supply actually needs to have two things specified about its output. The first is the voltage, and the second is either the current (in amps) or the power (in watts). It's a little difficult to buy a power supply for a computer unless you get one from the manufacturer, or one made for that model number. That's because most of them are not just transformers and rectifiers like they used to be. They are mostly electronic circuits called "switching power supplies". They each generate their own type of electrical noise, with which the computer must be designed to be compatible. So, the best bet is to buy a replacement from the manufacturer of the computer. Sorry that it's not just a simple answer.
