After getting clearing these 3 round they gave 3 cds and 3 weeks time.
Asked us to submit assignment on the subject on the cd.
the Cd consist of tutorial and lab exercise.

After submiting the assignment there is pre-assessement test and based on performance of assignement and test they will send for training(patni preparatory program ppp)..

The training will be 6 to 8 weeks and the stripen for the training will be paid along with our first month salary.We have to sign a two year agreement and also pay 75k refundable deposit. This deposit is refundable after 2 years.

About the written test is very easy question but no time.. it has three section.
1.verbal
2.analytical
3. technical
All the three sections are very easy but we have to rush with time. no negative marks.

The rule to follow it is try to solve as many question as possible.
i) first solve all easy question.
ii) dont read the comphension paragraph without solving all other question.

about the g.d.
patni g.d is a selection processs. They kept written test and g.d on same day. They just check the communication skill. people with some moderate communication skill will easily get shortlisted..
