After submitting an application they emailed me the next day asking me to complete a case study. It was very intensive for a first round “interview.” I hadn’t even talked to a real person on the phone yet. I sent my case study in and didn’t hear back for a few days. I followed up via email and they asked me to send more details showing my work. I sent them what they asked for and then they never answered any follow up emails until finally sending me an automated rejection email. I never spoke to anyone on the phone. For it being a first round thing, it is way too labor intensive. People’s time is valuable. Side note though is if you google the case study it’s all over the internet. Other applicants post about it and share what they submitted.
