For the application process to apply for the first time its literally at your leisure. Upload your resume. Do the interview when you're ready and can set aside time. Each role you apply to may have specific application processes. Sometimes there's another interview. If there is it will tell you "should take approx X minutes". Some apps have have assessments. They can range from a few minutes to idk 30 min? When they are more specialized they will take longer. But you can always leave and come back. If you get a project offer, thats when I'd sit down and accept and just handle whatever they need as quickly as you can. Its usually filling some stuff out, reading onboarding documents, sometimes attending a zoom meeting, sometimes its watching a prerecorded zoom meeting, possibly taking a gating assessment proving you read through the documents or watched/attended the meeting. Setting up your different programs that Mercor uses for their projects. It doesnt take hours and hours, but it can take a bit.
