I had a good experience interviewing with Indio! There are four rounds total, and I made it through three rounds.
First round - phone screen with the recruiter, pretty standard from what I remember. After the interview, the recruiter emailed me to set up the next round interview and also sent over an aptitude and personality test, said that I could do it right away but they didn't need it until I made it to the final round (full disclosure - I didn't do it since I figured there's no point in doing it until I confirmed I made it to the final round)
Second round - phone call with the hiring manager, took two tries since something came up for the original appointment. I really liked the hiring manager! Felt like it was a really candid and open conversation, they had a lot to say and really sold me on the company and role.
Third round - presentation and interview panel. I confirmed the interview details on a Tuesday and had the presentation/interview that Thursday, but I got the details for the presentation the Friday before while they confirmed their team's availability. The presentation was average in terms of difficulty. It's pretty vague, make of that what you will. I presented to the hiring manager I spoke to during the second round and another teammate. They gave me feedback right then and there, mildly terrified and definitely didn't expect that, but I learned a lot from getting feedback immediately. They gave me time to ask questions. Though I think I did alright, I left feeling like I didn't get the job, and alas I was right. I followed up with the recruiter a few days later, then a few hours later received an automated email saying I didn't move forward in the process.
Overall I thought it was a smooth process. The recruiter was helpful and thorough, even called me shortly before my presentation to double confirm that I was ready to go. A couple things to note - they don't send out calendar invites, so if you don't use a calendar already, make sure to write it down. The recruiter texted me once to confirm an appointment time, which at first I was thrown off by, but after confirming with a couple friends in recruiting, I found out this is not abnormal. I don't really like it just because I prefer keeping all of my communications on email so I can easily access it, but that's just a personal preference and nothing actually wrong on the company's part.
