Practice the timed screen
Before anyone interviews you, most companies send a timed coding assessment: several problems, one clock, and a score from test cases you mostly cannot see. Each format below draws a fresh set of problems and scores it the same way.
- Four problems, 70 minutesThe shape of a CodeSignal-style general coding assessment
Two quick ones, then two that take real thought. Most people do not finish all four; partial credit counts.
easy · easy · medium · mediumOpen - Two problems, 90 minutesThe shape of the coding section in an Amazon-style assessment
Fewer problems and more time on each. Passing every hidden test matters more than speed.
medium · mediumOpen - Three problems, 75 minutesA common three-question screen
One warm-up and two mediums. A good default if you do not know which format you will get.
easy · medium · mediumOpen
One easy problem and one medium. The result tells you which difficulty to practice first.
How it works
- The clock starts when you press Start and does not pause, even if you close the tab.
- Running your code shows 2 sample tests in full. The other tests only report how many passed.
- Each problem is worth the same and scores the share of its tests you pass, so partial solutions count.
- There is no interviewer and there are no hints. For a problem you could not finish, the result page links to the same problem as a mock interview.
- Languages: Python, JavaScript, TypeScript, Go, Rust, C#.
Assessment due in three days?
Invites usually give you a few days. One sitting a day is enough if each one is timed.
- Day 1Find out where you are
Sit the three-problem set cold. The result shows which problems cost you the most time and which tests you missed.
Three problems, 75 minutes - Day 2Fix what you missed
Open each problem you did not finish as a mock interview and work it through with the interviewer. Then do two more of the same difficulty.
Medium problems - Day 3One full run, then stop
Sit the format closest to the one you were sent, at the time of day you plan to take the real one. Do not start anything new after it.
Four problems, 70 minutes
The formats follow the publicly reported shape of common assessments: how many problems and how long. The problems and scoring are Placed's own and are not affiliated with any assessment vendor or employer.
