You screen-sharing on Zoom

Interviewer watching your screen

Undetectability may not work with some versions of MacOS. See our notice for more details.

Proof

Watch me get an offer from Amazon using Interview Coder. Throughout this whole video, you'll see me use Interview Coder for both the OA and the final round.

Undetectability

Here's how we ensure that Interview Coder is undetectable.

Pro

Screen Sharing

Completely invisible during screen sharing.

Webcam Monitoring

Move window around to overlay on top of your code editor so our eyes never wander.

Solution Reasoning

Every solution is explained step by step, and every line of code comes with comments explaining hot it works.

Active Tab Detection

Toggle the visiblity of the window while keeping your cursor on the interview tab.

Debug and Optimize

Debug your solutions

If the solutions are incorrect or you need an optimization, take extra screenshots of your code with ⌘ + H. Press ⌘ + ⏎ again and we'll debug and optimize your code, with before and after comparisons.

What I Changed (Read these aloud)

The current solution uses nested loops, resulting in O(n²) time complexity.
We can optimize this by using a hash map to store previously seen numbers.
This reduces time complexity to O(n) with O(n) space trade-off.

Solution

def twoSum(nums: List[int], target: int) -> List[int]:
    seen =   # Value -> Index mapping
    for i, num in enumerate(nums):
        complement = target - num
        if complement in seen:
            return [seen[complement], i]
        seen[num] = i
    return []  # No solution found

Complexity

Time Complexity: O(n)
Space Complexity: O(n)
