Criteo Associate Account Executive interview questions

I was referred by a current employee. I began talking to recruiter in January. Formal interview process began in March. I had a phone interview, took their analytical test, and had an "in person interview" via video conference call due to distance. All interviews went really well, I was highly interested in the position! After video interview I was asked to send my availability to fly to Boston to do a sales pitch. I followed up to thank those that interviewed me, asked a few questions, and sent my availability. They gave me a date that I would hear back about when i needed to come to Boston, when I didn't hear on that day I emailed the recruiter I had been working with. When I didn't hear after a few days I emailed again and called the office. I never heard from recruiter or anyone else in the company after that. Terrible communication and extremely unprofessional!

Applied via LinkedIn and contacted within a couple of days. Recruiter sent me an email about a quick phone screen. Said they would get back to me afternoon by never did. I interviewed twice with them and both times they failed to get back to me after initial screen.
