### 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 Answers 100 - 1 = 99 days This 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 Responses Starting 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!

 One of the interviews was with a guy from Brazil. Even though I actually speak Spanish, I had a very hard time understanding him. He asked a question about writing a parser (code something that will extract part of a string and put it in a hash to determine if it is a duplicate). I didn't understand everything he was saying, but didn't want to be rude, so I did the best I could, but I am pretty sure I missed some of what he was saying. 2 Answers first, they speak Portuguese in Brazil. second, if you can't understand you have to speak up. Duh! Of course they speak Portuguese in Brazil. There is some cross over between Spanish and Portuguese and in other situations, I had found a Spanish background helpful in understanding some Portuguese, but I didn't this time. You are also correct that I could have spoken up, which I actually did a couple of times, but decided to stop because, as I mentioned above, I didn't want to be rude.

 When you get higher throughput: while going at 5mph and while going at 50 mph? And Why? 2 Answers high 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.

Feb 3, 2013
 All questions were pretty normal for the intended position. Just that the interviewers were taken aback that I was over qualified and seemed purplexed by the whole thing knowing something wasn't right. 1 Answer No matter how much I said I'd still accept the job, they weren't allowing it. They infact said the position was below my skill level. Probably afraid I'd leave if offered something better.
