Johnson Controls interview questions

Initial screen call with recruiter (30 minutes), then call with hiring manager (1 hour) then a take home task based activity where I was asked to prepare a presentation. After submitting the presentation the company essentially ghosted me, never provided feedback on the presentation I submitted and only after multiple follow ups did I get informed (3 months later) that they decided not to hire for the role in the end. Very unimpressive and a definite lack of respect for candidates.
