I applied through university. The process took 3 months. I interviewed at IXL Learning in Dec 2013
Interview
I was introduced to IXL at my campus job fair. I went through three rounds of phone interviews spread over two months, each with a different member of the product management team. The interviews included general questions about my goals and achievements, science and math related questions, questions about pedagogy and the teaching process, and brain teasers (really fun!).
In the final stage, I was flown in for an on-site interview, which also consisted three rounds. I was asked to teach a topic of my choice to an imaginary 5th grade student. I was also asked to brainstorm ways to explain a concept to students at different grade levels. And of course, there were more brain teasers! I found my interviewers very friendly and warm, and at the same time, keenly attentive to my answers, reactions, and questions. I thoroughly enjoyed the interview process.

Question 1
What do you see as a possible downside of this job?
I applied through an employee referral. The process took 8 weeks. I interviewed at IXL Learning
Interview
Process took ~8 weeks in total. Applied through Jobvite, had reference from a current Product Analyst. Got phone interview, no unexpected questions, similar to those described in other Glassdoor reviews, complete with jelly bean brain teaser. Was given job test, which I spent the full week on. Was called in to on-site interview - 3 hours, 3 different people, all very nice and asked fair questions about my background, teaching experience and how I would generate questions for the problem generators. Pretty exhausting though. Was then called into a second on-site interview to meet the other Science Product Analysts and had another interview with the heads of the team. After a few days, was sent email expressing that I was "not a match". I was utterly baffled by this decision, as I'm well qualified for this position, every interview had gone well, and they had expressed several times that they were "very impressed" by my performance. No clue what they're looking for.

Question 1
Most difficult question was second brain teaser asked at on-site interview.
I applied through university. I interviewed at IXL Learning (Los Angeles, CA) in Oct 2014
Interview
Interviewed during campus recruiting. Interview only lasted 30 minutes and seemed rushed. Recruiters were very friendly and kind but Interviewer was awkward and inexperienced. I wasn't surprised by the question content but thrown off by how uninterested the interviewer appeared.

Question 1
Demonstrate how you would teach a science concept of your choice to a third grader.
I applied online. The process took 4 weeks. I interviewed at IXL Learning (Foster City, CA) in June 2014
Interview
I applied to the Product Analyst position online without knowing anyone at the company and got notification that I'd be having a phone interview within about a week of my application.
The phone interview had all the standard questions (Why IXL?, etc) in addition to a brain teaser. I was also asked to describe my PhD research as I would to a kid in 4th Grade. I was notified at the end of the phone call that I'd be advancing to the next round, the skills test.
They emailed me the skills test with a few questions for me to answer at home over the space of a week. The questions were, apparently, a fairly good representation of the type of work you'd be doing for the company in this position. I did my best but was a little unsure about how I'd done, but it must have been good enough because within a few days I was notified that I would be advancing to the on-site interview round.
The onsite interview lasted about 2 hours. I met with 3 different people; a math product analyst, a science product analyst and a director. You are just left in one room the whole time while the interviewers come to you, but they give you some puzzles and reading material about the company to keep you entertained while you're waiting. The two product analysts were very heavy on skills questions, very similar to the take-home skills test but you are expected to answer on the spot. You're given an example of a problem that might appear on the website then asked how you would vary difficulty on this problem, what other types of questions you might ask and how you'd make it more engaging. The director asked more typical interview questions about past conflicts/resolutions at work, why I want to work at that company, what experience makes me the ideal candidate, etc.
In the end, I was left feeling unsure how I'd done but didn't feel like I'd said anything too stupid. I didn't get an offer so I don't have any useful advice about what they may be looking for.
