Matrix PDM Engineering Engineer interview questions

Way too slow and few updates. Interview 3 happened more than two months after Interview 2. My follow-up email between those interviews went unanswered for at least 3 weeks. I was promised a quicker update after Interview 3 which happened more than 2 months ago. I did note recently that the job posting changed in such a way that excludes my candidacy, so why was I not informed? All in all, the interviews themselves were okay, but my time was not respected.
