Element Solutions (FL) Process Engineer interview questions

Macdermid in San Jose/Fremont. 3 stages: recruiter screen, hiring manager screen, and panel interview onsite. Reasonable interviews but long stretches (2-4 weeks) in between and before feedback after the final interview. I interviewed last year and was completely ghosted after my final round. This time they told me they were offering to another candidate, then that candidate declined, then they will be reposting the same job at a lower salary. Waste of time
