yesterday we practiced some topics on GD and had some tips on PI  
GD &PI the important words for job    if u want a job u have to crack GD &PI ------------------
GD------- group discussion ----------in which a group is given a topic and u have to give your points on that topic but don,t argue with anyone there are many dos and don't s u should not say anyone that u r wrong  or i don't agree with u or no its not like this __________
u must speak your point loudly and confidently try to give more and more points but don't have point to point discussion i.e fight in two people on some point  ----
PI--------------------personal interview ----------in this u have to go in front of hr and represent yourself   first knock the door and go in wish the hr with a cute smile and don't sit until he says u sit and thanks him for offering the seat and then ans all the questions he ask try to admit if u don't know anything say it i don't know admit it its good u must know your strength and weakness and try to present your weakness in positive way like u are lazy u can say  i m lazy but to overcome this i set my goal and complete it on time and similarly u can say something positive with your weakness okkkk
