Iterable Solutions Consultant interview questions

Had a first stage interview that I believe went well and answered all questions asked professionally. At the end of the interview I was told that I would be contacted next week to schedule a time when I could speak to the necessary manager who would be interviewing me for the 2nd interview, essentially confirming my thoughts that it had gone well. The next week I receive an e-mail from the company saying that they're heading in a different direction. Now, they have every right to do so but I do think it's unprofessional that I be told that I have another interview with them and then it turns out not to be the case. If the interviewer said that they would relay their notes they've made back to the manager and discuss whether I was a good fit and then let me know, absolutely fine. This is what I've experienced in most cases when interviewing for roles. This might be an isolated case but from reading other reviews on here aroud interviews and from ex-employees it doesn't seem too far-fetched for this to be standard operating practice for potential candidates. Be aware, they may say one thing during interviews and change their tune after.

Phone screen with the hiring manager, followed by an onsite with members of the team, director of the division and a presentation on the subject matter, in this case integrations. The team hosted me for lunch, and gave me a tour of the office.
