inSegment interview questions

One online questionnaire and one test upfront, without meeting anyone before that. The test consisted in a lenghty analysis and optimisation for several google ads campaign (6 h work minimum). I sent general suggestions. A video interview followed. After ut, the interviewer asked me to analyze in detail the campaigns and propose optimisations because they wanted to see how I think. I sent back the analysis for 2 campaigns (out if around 6 whith many adgroups). I had a final interview with the director where he offered me half of the salary range I asked for. A complete waste if time on my part. Maybe they should either stop asking salary range if they are going to disregard it, or maybe publish it with the ad.
