4 rounds. HR screening -> Case Study -> Case Study Review -> 2 back to back interviews
The HR screening was a 45 min call with HR to discuss the role, your relevant experience, compensation. It's very straightforward if you do the assigned work they give you.
The Case study is 1hr of working through a mock client request. Youre tasked with "asking" questions to the client, thinking through target expert groups, actually finding 2 names on LinkedIn and drafting an email to the client summarizing your findings.
The case study review asks you to go over the logic behind your choices. They ask what you might have done differently. They expect you to know what a priority request for the company is vs something that could be dealt with later (client request vs manager feedback).
The back to back interviews are mostly behavioral: how do you work in teams, how you do deal with uncertainty, a time you were persistent in finding a solution, experience with cold outreach. They may go through a second mock client request where you're expected to come up with a creative solution to a not so straightforward request.
They got back to me the same day about moving on to the next rounds except after the final interview (3 days and a follow up from me). I sent thank you letters to everyone and made sure to thank everyone for their time.
I'd rate the difficulty a 3.5/5. They threw a decent amount of soft ball questions and was only caught off guard a couple times in 4 rounds. It was very smooth overall. From screening to offer was under 3 weeks.
