### Senior Systems Test Engineer at Qualcomm was asked...

 There is a body of water that starts with 1 square unit, and doubles in size every day (2 units after 2 days, 4 units after 4 days). It takes 100 days to fill up. How many days would it take to fill if you started with 2 square units?6 Answers100 - 1 = 99 daysThis question is phrased incorrectly. I think you meant "4 units after 3 days". Which makes your answer wrong as well. This is not helpful at all.if you start with 1sq unit - lets say you end up with 'x' amount to fill up - takes 100 days if you start with 2 sq unit - you will have to fill up '2x' amount thus it will take - 200 days.Show More ResponsesStarting with 2 square units at time t=0 is like 1 square unit at t = 1. [this logic is the key to answering the question]. Now let's do the first few cases. t = 0: size = 1+1 = 2 t = 1: size = 2(1+1) = 2+2 = 4 = f(2) in the 1 unit case. Pretty easy to see it only requires 1 time period less from here. The OP was right.1 day less that is 99 days.It is still 100 days. Starting from 2^0, and going all the way to 2^100, the reservoir has a capacity of 2^101 - 1 units. Now in the second case, starting from 2^1, in 99 days there will be 2^101-2 units of water in the reservoir, which is one unit short of the capacity of the reservoir. So we need the 100th day to fill it up!

 All about resume, why SCFDMA in uplink, PHFICH channel frequencies, what happens in MRC, LTE call procedure.2 AnswersNeed to know wireless communications, digital communications concepts in and out.The key in these questions is to cover the fundamentals, and be ready for the back-and-forth with the interviewer. Might be worth doing a mock interview with one of the Qualcomm or ex-Qualcomm Modem Systems Test Engineer experts on Prepfully? They give real-world practice and guidance, which is pretty helpful. prepfully.com/practice-interviews

### Wireless Systems Test Engineer at Qualcomm was asked...

Mar 23, 2011
 When you get higher throughput: while going at 5mph and while going at 50 mph? And Why?2 Answershigh mobility communication is more difficult.You will get higher a throughput while going at 5mph. Higher speeds indicates that the RF channel conditions such as delay and Doppler spread are changing at fast rate and its a fast fading channel. It is difficult to achieve equalization in such situation. Hence the modulation scheme can be shot down to, say QPSK(2 bits/symbol) from maybe 16QAM(4 bits/symbol) to provide a more robust transmission. This brings down the user throughput.
