Emery Oleochemicals interview questions

The whole interview was not comfortable. The so called hiring manager is so bossy, unfriendly, pre-judgement. I found it un professional. If that is the case, why call for an interview?

Started off process that dated 90 days ago . TWO interviews with HR and tour of facilities on-site. On-site tour of IWTP , to see if your a good fit, a line of questioning from supervision. They have given me information but no other Details as duties of the job description. You must wear street clothes WITH PROTECTIVE GEAR, GLASSES , HARDHAT, STEELTOE BOOTS nothing over dressed to walk into facilities for its dirty and a fatty acid factory. 2nd tour is contingent on factors beyond applicants control. Hiring process seems to be hidden from applicants. I already had certificates Emery Oleochemicals were interested in for their purposes of hiring .
