You'll complete an online application and upload a cover letter and resume. If you appear to be a match they'll send an invitation to complete a project that is supposed to be similar to the work you would be doing if hired. If they like your work on the project, you'll be invited to a phone interview. Depending on the level of the job, you could have more than one phone interview, an in person 1-1 or panel interview. Interviews follow a script and they write down your answers to evaluate them later, probably against a rubric.
