hi, im karthik frm madurai.
indiabix helped me a lot in my interview preparation with infosys, ill help u guys frm my side..
2 rounds
1. onlinetest by infosys
2.tech/ general HR.

ONLINE TEST consist of 3 sections,
1. reasoning -15 qns -25 mins
syllogism -5 qns
data interpretation( graph, bar chart, or table)- 5 qns
data sufficiency - 5 qns.
This round is not really tough, u shld know how basic syllogism shld be solved, only prior practise can help u. four syllogism groups will be given and u need to find the group(s) that are actually correct.
data interpretation qns will be simpl with ratios and percentages comparing two different years.
Data sufficiency is really easy, simple twist,try solving tough questions from this section ,so info qns will be easy for u (more on equations, numbers ...)

try to get atleast 10 to 11 questions correct in dis section , dat is more than enough..sectional cut off is there..so try getting minimum marks in all the section.

2.Aptitude -10 qns -35 mins
puzzle-5qns ...this one will be toughest part of info ,i guess..it s a kind of arrangement question ,..but questions based on that arrangement part will be really tough..i dont get ans for any questions...so practise a lot in this section..try solving GRE ,GMAT type of toughest arrangement questions...

general apti qns: number series -1 qn
crypt arithematic - 1 qn
other 3 qns from probability, permutation combination,alligation and mixture
if u r good at solvng apti, then dis s just a cake walk..but if u r not good at it,,try solving the tough qns and understand the concepts foremost,...on apti...crypto takes more time..u can solve only if u had practise..series will be moderate...

i felt this section tough coz im bad at apti... try to get 6 or 7 qns right..
try solving the easier one first and then go for the toughest problem..so u can get enough time to solve the problem. concentrate in this section if u r bad at apti.

3.verbal 40 qns -30 mins..
this section is not really tough as othrs say,,..they ll not ask GRE level tough qns....
actually the questions will be simple..but confusing...it needs the basic understanding of english..if u r good at english,,then this will not be really tough.

sentence correction-7qns
insert correct phrase - 7 qns
fill blanks - 8 qns
theme detection -5 qns
reading comp-1 (small) -5 qns - lil tough
reading comprehension -2(big) - 5 qns -easy but takes more time..

frankly speaking one cannot complete this section,,so u need to go for the one which u can answer easily, theme detection, fill blanks, will be easy.. and error correction will be moderate,,simple but confusing,,all the answers will look in shuffld type,,which shows all are correct answs, reading comp takes more time..so try at last,,go for the questions and then look for answers.

most rejections happen at the first round,if u r selected in ur first ,u ll be almost selected (around 85% will be selected)in second round,,so if ur dream job is info..then practise it bfore u attend the test,,last min practise will never help u.

2. technical interview/generasl Hr:
im from mechanical dept,,and it is based on ur panel whether they ask u programming relatd qns or not,if u r from non cs/IT then,u ll asked to write som prog from basic c, for cs and IT,, they ll hav qns relatd to thier subjects..
again it depend on panel u enter, for me..they havent asked any program, he just asked me all the questions from my resume..my areas of interest, latest technology, my project, and general HR qns lik y info ? y frm mechanical ?(get good ans for dese qns )..
mine was very simpl..but for some they asked the basics qns of thier core like free body diag frm my core...and again depends on panel.. even if u donno ,u jus try to solve the program,,,they just check for ur communication skills,,im not threatening u..but i wanted to say luck also favours in these type of interviews to decide which panel u r going..

finally, i got selected and im INFOSCIAN now (happy to write coz whenever i read interview exp, everyone concludes with this..) i wish u all good luck :)
