Similar to what others have said. 3-day deadline for a take home interview to write a test plan. No guidelines or other instructions given. Just pick a mobile app and write a test plan. Add a bug report if you find one.
I got a screening call afterwards, with the BA/hiring manager. Not only was he 12 minutes late, but it was extremely noisy in their "shared workspace". It felt like he was reading questions from a script, and very uncomfortable when I asked anything (about team structure, opportunity for growth etc.). An awkward, unpleasant experience overall.
Heard back several days later that I wasn't accepted, very competitive process etc. They've been posting the same ad on LinkedIn for a few weeks now.
