Wapda interview questions

Introduce yourself? What are amino acids? What is 1st law of thermodynamics? Name any two basic amino acids? What are zwitterion? Why zwitterion are called internal salts? Why red colour light is used for the indication of danger?

Interview was just formality. They have already sold out the seats. No merit. Question were asked just for formality. They said you are over qualified for this post. You won't fit here. Try your luck at some better place.
