Implementation Specialist interview questions shared by candidates### You have a bouquet of flowers. All but two are roses, all but two are daisies, and all but two are tulips. How many flowers do you have?

44 Answers↳

3 flowers - 1 rose, 1 daisy and 1 tulip

↳

The solution is quite simple, if you start with the “All but 2” first: Roses = All but 2 = Two flowers are not a rose; one tulip, one daisy Daisies = All but 2 = Two flowers are not a daisy; one rose, one tulip Tulips = All but 2 = Two flowers are not a tulip; one rose, one daisy Answer: One rose, one daisy, one tulip.

I would say, "Do you consider three flowers to be a bouquet?"

### How many minutes before 5pm is it if 30 mins ago it was four times as many minutes after 3pm?

11 Answers↳

The answer is 18 minutes. It made sense to me to sketch a timeline showing the 3 components of time given in the problem that add up to the 120 minute total span. (X = minutes before 5pm, 30 min gap, and 4X is time between 3pm and the start of the 30 min gap.) Visually and chronologically it would look something like: 3pm --> 4X --> 30 min --> X --> 5pm. So then algebraically, the equation is 4X + 30 min + X = 120 min. Therefore 5X = 90 or X = 18. Less

↳

18 mins before 5 = 4:42. 30 before 4:42 puts the time at 4:12. There are 72 minutes between 3 and 4:42 divided by 4 is 18. So the answer is 18 mins before 5pm. Less

↳

That last explanation seems like you need to know the answer before you even start trying to solve. My solution is as follows: 30 minutes before 5 is 4:30 leaving 90 minutes between 3 and then. The remaining time needs to be split into an interval so that x4 exists. The most logical interval would be in 5ths because the 4 proceeding intervals would be 4x greater then the following. 90/5=18 for each interval. 18 being four times less then 72 minutes proceeding it. This literally look me about a minute and a half to reason through, which I'm assuming the interviewer would not want to sit through. Guess I would fail. Less

### An apple costs 40 cents, a banana costs 60 cents, and grapefruit costs 80 cents. Under the same circumstances, how much does a pear cost?

8 Answers↳

40 cents... it's 20 cents per vowel, not 10.

↳

40 cents. 20 cents for each cents.

Hey Blake - while that answer is very creative, this particular question was given during a 12-question-3-minute math test. I'd say that you might have a hard time writing all of your economics answer down in three minutes. Nice answer, though! Less

### In pseudocode, write a function that takes in an arbitrary string of lowercase letters and an integer n of 0 or more. Return the number of times the character 'a' appears in the string, reading in n characters from the string, in order. If n is greater than the length of the string, loop back to the beginning of the string upon reaching the end.

4 Answers↳

Iterating over the characters in the string, and counting the number of times a character appears. The index into the string was determined with mod n. Less

↳

taking in characters 'n' at a time is kind of irrelevant in the beginning it just shows you how many you need to take from the beginning of the string once you've gone through the entire thing. So make a variable like int redo = myString.length % n; Go through looking for the character 'a' and incrament a counter. Afterward, iterate through again from beginning until less than redo and return. Less

### Given a 3x3 grid arrange the integers 1-9 such that each row, column, and 3 element diagonal, sums to 15.

4 Answers↳

Really easy. You should immediately realize that 9,8, and 7 have to go on the diagonal. Less

↳

never mind, diagonal also had to add to 15 lol

↳

Start off by ensuring that no two numbers of 9,8, and 7 share a row, column, or diagonal. After that, it is easy. Less

### There are three buckets, one with apples, one with oranges, and one with a mixture of both. They are all labeled wrong. You can pick one piece of fruit from one bucket, what would you pick to determine what is in all three buckets?

4 Answers↳

I posted the question, sorry, I should have answered it. You pick a piece from the basket labeled "mixed." This is because you know it is labeled wrong (every basket is). So, if you pull out an orange you know that the basket holds only oranges. Now you have one basket figured out, and you know the remaining two are also mislabeled, so you switch their labels and you're done. Less

↳

The question should state that the label always lie. If the label says "Apple Only" it could be "Mixture" or "Orange only" So the one labeled "Mixture" is either "Apple Only" or "Orange Only". So you choose Mixture and what ever fruit you get is the label that is correct. Then switch the other two. Less

↳

All of the answers are close but not entirely correct. Any box is labeled incorrectly. Choose the mixture box. If you pick out an orange, it is necessarily an orange only box. The other two must only be the mixture or apples only. The mislabeld apples only box must be the mixture because it is mislabeled and there are only 2 other choices left. The last box is the mixture. This is the order in which you must think, although the particular fruit you pick up first could be either apple or orange. Less

### What is the angle between the minute hand on a clock that reads 3:45

3 Answers↳

The angle between the minute hand and the hour hand would be 157.5 degrees. Each 5 minute segment is 30 degrees, and at 3:45 the hour hand would have moved 3/4ths through one of the segments. So there would be 5 and a fourth. 5*30 = 150, 30/4 = 7.5, 157.5 total. Less

↳

Matt's answer is definitely right. To explain more fully so it's clear to Han and others: At 3:45 the minute hand would be pointing to the 9, the hour hand will have moved 3/4ths the way towards the 4. If the hour hand were still at the 3 the answer would be 180, if it were all the way at the 4 it would be 150. So we would expect the answer to be closer to 150 than 180 degrees which is more in line with Matt's answer. Since the angle between 3 and 4 is 30 degrees, each fourth would be 7.5 degrees. Matt went from 150 (angle from the 9 to the 4) and added 7.5 for the last fourth of the angle to account for the angle between the 4 and the hour hand. 150+7.5 = 157.5 Han started at 180 degrees and tried to subtract the angle between the 3 and where the hour hand is, but took a shortcut and used Matt's 7.5 (1/4th the arc) and subtracted it instead of using 22.5 (3/4ths of the arc). 180-22.5 = 157.5. Drawing it out also helps if you are confused. Less

↳

Matt's thought is correct, but his answer is wrong; final answer should be 180 - 7.5 = 172.5 Less

### If you have unmarked two buckets which you know are 3 and 5 gallons in volume and an unlimited supply of water, how would you get exactly 4 gallons of water?

3 Answers↳

1. Fill 5 gallon bucket 2. Pour water from 5 gallon bucket until 3 gallon bucket is full 3. Empty 3 gallon bucket 4. Pour 2 gallons of water from the 5 gallon bucket to the 3 gallon bucket 5. Pour 5 gallons of water into 5 gallon bucket 6. Pour 1 gallon of water from 5 gallon bucket until 3 gallon bucket is full Less

↳

Pour water from bucket 1 into bucket 2. If bucket 2 overflows you know that bucket 1 is 5 gallons, otherwise bucket 2 is 5 gallon bucket. Now empty both buckets. Pour 3 gallons into 5 gallon bucket, then refill the 3 gallon bucket. Fill 5 gallon bucket until it is about to over flow (leaving 1 gallon left in the 3 gallon bucket). Empty the 5 gallon bucket and fill with the 1 gallon of water that is in the 3 gallon bucket. Refill the 3 gallon bucket and pour the 3 gallons into the 5 gallon bucket. You now have 4 gallons of water in the 5 gallon bucket. Less

↳

Fill both Buckets exactly half way 1.5 Gal + 2.5 Gal = 4 Gal
