7.5 degrees. The hour hand would have moved past 3 in order for it to be 3:15.
Time for me to go
Depends on the clock. For starters let's assume it's an analogue display. If the hour hand only moves on the hour as opposed to at a set rate around the clock, then it would be 0. If it moves at a set rate, then the angle would be 7.5 degrees. (Full circle is 360 degrees, 12 hours on the face so it moves 30 degrees every hour or 7.5 degrees every quarter hour).
Near enough to 0 to not worry about, I am sure there is a website with a more accurate answer if you really want to know. This is interesting as the question is/was "If the time is quarter past 3, what is the angle measurement on the clock?" What are we measuring? If everything was plumb and level then it might 90 degrees. I know the table my digital clock sits on is not level but I have never measured the wonkyness of the table.

I really don't care
Presumably the interviewer is asking for the angle of the hands on the clock taken from the midpoint therefore the correct answer is 180 degrees. If the time was three o'clock then the answer would be 90 degrees. Some of the answers here make me question what is being taught in schools these days, I don't mean to sound patronising but I remember my angles from my Primary School days which were in the 1970s!!
Gillian, Please put on this nice pointy hat and sit in the corner.... Quarter past 3 = 180 degrees? Are you sure about that?
90 degrees acutely and 270 degrees obtusely
No scrub that the answer I gave was for 3 o'clock. 3.15 would be 7.5 degrees or inversely 352.5 degrees.
It's on the right hand side about a quarter of the way round the clock.
The minutes hand stood at 90 deg the 15 minutes lapse will move the hour hand to 90 + (15/60 * 30 deg) = 97.5 deg difference = 7.5 deg

Somewhere between minus and plus infinity. Modulus 360 degrees, of course.
7.5 degrees. The minute hand will be 90 degrees past the vertical, the hour hand (which moves 30 degrees per hour) has moved 3.25 * 30 degrees since noon so is at 97.5 degrees past vertical. Difference = 7.5 degrees.
Well each hour mark on the clock is 30 degrees from 12pm. The hour hand moves 30 degrees per 1 hour, 15 degrees per half hour, 7.5 degrees per 15minutes. The minute hand is at 90 degrees from 12pm and the hour hand is at 97.5 degrees from 12pm. The difference is then, as many others have said, 7.5 degrees.
Because I'm smart, enthusiastic and believe I can bring a lot to the company
I’m an enthusiastic, quick learner. I can bring a lot to the company as i attire a large variety of skills. I can easily adapt into different environments and work well within a team, which is an important aspect when working here
1. When any candidate submit a solution they should come back with review. I posted all automation solution to google drive and shared with three CA people. None of them sent me any feedback about the technical solution that I submitted. 2. Second round was technical - I assumed that they would gothrough my solution and ask quesitons around that. But strange thing is 30 mins back before interview the interviewer asked for the google drive permission. Later they did';nt ask any quesiton around that. Note : The way I solved the problem was in-detail and these guys did;nt get what I have submitted. In my solution added. end to end automation approach for WebUI and API and thoughts that we can implement further by a.Instanbul code coverage. b.CircleCI integration c. Parallel test wich cypress d. percy snapshot testing. e. Postman neman integration f. load test with K6 I even went ahead and crashed the server as well. No one noticed and they did'nt even acknowledge. End of the day What I understood is that the interview panel is not technical. they did'nt get what i am saying. There QA tech stack is not great. Basically they dont need too much technical QA guys. Thanks
I had the same experience, they did not bother to look at the solution shared ! Was very disrespectful when i had put so much effort to do the task they did not even look !
The database size would determine the downtime needed to perform the migration.
Multiple factors affect downtime. You should start with planning an approach that minimizes it by taking into account factors like DNS changes, network latency, data rate of change and of course data set size too. Replication and load balancing could be other factors. The more points you mention and consider, the better the answer.
