I was contacted by email, and invited for an interview. The interview was sufficient and asked behavioural and skill based questions. I thought it went very positively and awaited feedback. I didn't hear anything for two weeks, so I emailed one of the recruiters and received an out of office, I then proceeded to email their 'out of office' contact person (Recruitment Lead) who said they would schedule a call with me and never did. After leaving both a voicemail, and one more email, I gave up. I found the experience negative and unprofessional.
