The first technical screening involved completing a timed coding challenge that had a soft deadline of around 45 minutes. Unlike other challenges I've done before, it was hosted on DMOJ, an online coding competition platform. If you haven't worked with DMOJ before, I encourage you to try it out and get comfortable with it before attempting the challenge, as running tests and debugging on the platform may not be intuitive to all (it lacks an in-built IDE and the interface is more of a text editor if anything). However, the founder does leave a pretty good video guide before you start the challenge, so definitely give that a watch.
Interview questions [1]
Question 1
Given n lines of logs (in the format `worker_id, timestamp, action`, where worker_id identifies the worker completing the action, timestamp indicates when the action occurred and action being either "sign-in" or "sign-out") and an integer m, maxSpan, return a list of all worker_ids such that the time they've worked is equal to or greater than m.
Coding assessment on their site, it wasnt too hard as the hardest part was really setting up the environment locally to test the code but the questions itself were easy leetcode questions
I applied online. I interviewed at Wanderlog in Jan 2026
Interview
Terrible experience.
They send you a coding assessment and claim it’s not LeetCode-style, saying it simulates a real-world scenario. That’s simply not true. The questions are essentially LeetCode problems, and you’re expected to solve two questions in 40 minutes.
The questions themselves aren’t difficult, but the platform is clumsy, and the instructions are confusing. You also have to download files, which takes additional time and eats into the already short window.
I completed the assessment over the weekend and, just a few hours later, received the standard “we’ve decided to move forward with other candidates whose experience and skills are a closer match” email. Honestly, that response felt generic and automated. It’s very unlikely my submission was reviewed that quickly over a weekend. All tests passed, and there were no issues with my solution.
My advice: don’t waste your time or energy on this company.

Question 1
One of the questions was a frequency-count and sorting problem, which is very typical of LeetCode-style interviews.
