ok so I just finished the EA online assessment and phone screen process and I want to dump everything I remember because I was desperately searching for recent info and couldn't find much.
The OA (online assessment). Hosted on HackerRank, two problems, 90 minutes. You get the full time even if you finish early, so don't rush and miss edge cases. Mine were: A graph problem. Given a set of game servers and latency between them, find the path that minimizes max edge weight (basically a min bottleneck path variant). Not a pure shortest path, closer to a modified Dijkstra or Kruskal. A string manipulation problem. Nothing fancy, felt like LC medium string operations. Process input, handle edge cases, output formatted result.
Overall difficulty: solid mediums. Not easy mediums where you just brute force, but nothing that required obscure algorithmic knowledge. I spent about 35 min on problem 1, 25 on problem 2, had time to clean up and double-check.
Things that helped. Making sure my solutions handled the edge cases they explicitly listed. Their test cases do hit things like empty input, single element, etc. Write clean readable code, not hyper-optimized. I used Python, no issues.
The phone technical screen. This was a 60-minute video call. First 15 minutes: talking about my projects and background. Then a LeetCode-style problem on a shared coding environment. Mine was a sliding window / two-pointer problem, again medium. They asked me to talk through my approach before coding, which I appreciated because I'd prepped for that.
After the coding problem, the last 10-15 minutes were behavioral: tell me about a time you dealt with a bug under time pressure, tell me about working on a team that disagreed, etc. Pretty standard but they actually followed up with "what would you do differently" which caught me a little off guard.
Timeline for me. Applied through their careers site, heard back in about 10 days. OA link came same day as the email. OA results to phone screen invite was about a week. Phone screen to next steps was 2 weeks (felt long but they were apparently running multiple parallel loops).
I'm still waiting on whether I'm moving to onsite so I'll post an update if I do. If you've been through the full onsite recently, please drop your experience below.
