Awkward, unprofessional interview.

First, a guy contacted me and tried to schedule a time for a short talk. He sent me the wrong job link, then fixed it. After that, he sent two incorrect invitation emails and finally provided the right link after 24 hours.

At the scheduled time, I spoke with him on a noisy Skype channel. After he introduced the position, I was suddenly asked to answer some basic algorithm problems (e.g., describe A*, heapify). I also had to code on a shared Skype screen.

After the first call, another guy wanted to give me a "30-minute quick chat" the next morning. I had to send him an email to verify the time zone. He was 15 minutes late, and the "30-minute quick chat" turned out to be a one-and-a-half-hour coding interview on a shared screen via their website. I had to open my IDE to code. He said I should write some tests for the code and send them to him so he could schedule an onsite interview.

The next morning, I canceled my application on their career website.
