Nestlé Process Engineer interview questions

the interview itself was rather difficult, we had to interact on a real case studies, several interviews, but good atmosphere and qualified people giving the interviews. Human resources were useless

I got called by a nestle recruiter about this position. After a fairly expedient process with two phone interviews followed by an onsite interview I heard silence. I assumed I didn't get the job, but the recruiter stopped responding to e-mails. My assumption was confirmed when Nestle called me about a month later trying to put me through the interview process for another position. I declined to indulge.
