Hi there, few days back i had an interview with OPI Global(Outsource Partner International). The first round was suppose to be written Test. I wasnt sure about what kind of questions will be asked, so i just googled for the same but did not find any appropriate results or may be i was not able to find it. So basically I am gonna write about the questions and their level of difficulties with a few sample questions. basically there are 5 sections and total 40 Questions: 1. General English 2. Computer Skills (Mostly Excel) 3. Analytical 4. Aptitude 5. Finance & Accounts Sample Question Section 1 Ques - I stay ___ the city center Option - a. by b. near c. nearby d. Ques - I ___ television this evening Option - a. saw b. view c. watched Section 3 The question was too long so i just cant write here but can tell you the level of difficulty. It was pretty simple but you just need to read it care fully and you would be able to solve it easily. Section 4 I am not very good at aptitude so found this section little tough for me. Question - If 10 ppl can finish a work in 10 days then how long 8 ppl will take to finish the 3/4 of that work Option - I dont remember. Question - Car A runs at a speed of 40 miles and leaves the city at 3.20 PM, Car B runs at a speed of 50 miles and leaves the city at 4.40 PM. At what time Car B will catch Car A? Option - I dont remember the options Section 5 I just cant remember the questions but would suggest you to read abt personal, real and nominal accounts. Read little bit abt depreciation and basic stuffs.
