Amazon Area Manager Interview
Phone screening Math Flow question: You have 30 associates, 2 are not on the production floor. Each can process 150 UPH; Each works 8 hr days, 5 days week; each day each worker is given 2 15 min breaks. How many units can they output per week?
30 Associate - 2 NUPA (Non Unit Producting Associate) ----- 28 Associates in Production ----- 8 Hour Days - (2) 15 min breaks = 7.5 hours of production 28 Associate X 7.5 hours X 150 UPH = 31,500 Daily UPH X 5 = 157,500 Units per week. --------
After reading and figuring out my answer is 157,500.

Cant read into what most companies do, just have to focus on the data given as just that GIVEN. 30 EE 2 Non Production 150 UPH 8 hour day (-30 min break, so 7.5 hr worked) 5 days a week 28 EEx 7.5 x 150=31500 p/day (31500 x 5)= 157,500 Powers formula P=W/R/S can solve just about anything they throw at you mathematically
Subtracting the 30 mins break from the 8 hrs, the working hrs becomes 7.5 hrs. therefore, 28 (men working at the rate of) *150(units per hr, for )*7.5(hrs in one day , for)*5(days in a week) is the answer: which is : 157,500 units.
I got 157,500 units
My answer came out to be 157,500 for the week of working 5 days 7.5 hrs/day... with 150 units per hour and 28 AAs.
So no lunch, just two 15 minute breaks? The other two employees are on vacation and will not get figured in the production for the week. Figuring at 7hrs of production, each person produces 1,050 units per day or 5,250 per week. Your total team production on the floor produces 147,000 units per week. If no lunches and just two 15 minute breaks the team production will be 157,500 units.
so how was the question ? the answer is 157.500 not 137,500
Answer is 158 970
Are they working 8 hours per day or 7.5? Most companies have you work 8 hours and give you 2 -15 minute breaks and a half hour for lunch. If you are working 8 hours, you are on site for the additional time you receive for breaks or lunch so, in this case they would have 8 production hours and be on site for 8.5 to account for the breaks. I read this as working 8 hours. So 8 hours x 28 employees x 150 UPH x 5 days= 168,000. Am I overthinking this?
The answer is 137,500..
So the answer is 137,500 unit in a week
Each worker works 7.5 hr days for a total of 37.5 hr weeks. You have 28 production workers X 37.5 hr weeks = 1050 production hrs. Multiple that times your 150 UPH for a total of 157,500 units each week. Question is very straight forward. Hear the math flow during the onsite visit is much more complicated, will post details after interview.
