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.

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.

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.

You're forgetting the part where it says: "30 mins ago." It's not four times as many minutes since 3.

120 - x - 30 = 4 * x

The correct answer is 24. 120 minutes between 3 & 5; 120 divided by 5 =24. 5pm less 24 minutes = 4:36pm 3pm plus 4 times 24 minutes (96 minutes) = 4:36pm
