Mendeley Test Automation Engineer interview questions

Interview process for role is telephone interview with two staff members. a marathon technical set of face to faces to last 'up to 4 hours' and then if all still good. A 30 minute call with the big boss in another separate session. All a bit much when they're just looking for a short term contractor I pulled out at phone interview stage as they were almost ten minutes late making the call, they never introduced themselves or said what they did until I was able to drag it out of them and they and obviously had no experience in interviewing full stop, let alone interviewing for test professionals. I was not asked any technical questions and it felt like they were just reading from a script with no understanding of the questions they were asking. Seemed they were interviewing for a manual tester or project manager role and did not know what they really wanted. I was not asked a single question about test automation or anything in their 'essential skills' list. Hopefully they'll improve based on other glassdoor reviews I see and wish them all the best. For now I know, I feel like I've dodged a bad egg
