Illumina interview questions

After applying I got a reply within about a week that they read my application with "great interest", but then I did not hear again from them for two weeks and received no responses from them after telephone calls and e-mails. Then they contacted me again and a telephone interview was arranged within a few days. This was straight forward. The opportunites were described and how I would fit in the company. Then there was a three week silence and I gave up on trying to contact them. Then an interview day was arranged for which I was asked to prepare a presentation. Several 1-1 interviews were also arranged. Some interviews contained technical questions while others were more a chat about the company and opportunities within. Since this day my travel expenses were duely reimbursed, but I have not heard back Since then, over 6 weeks, no correspondence. I do not think it bodes well if a company cannot even adhere to simple rules of politeness such as returning phone calls. How must the climate be within the company? I did also not get a good impression of the work culture. When an interviewer says that their childcare arrangement from 8 to 6 is barely sufficient and another says that arrangement of part-time work is difficult, then this is not a family friendly climate. The work culture was also quoted as work hard, play hard. This might suit many people well, but those whose life is not solely defined by their job and who are looking for a good work life balance, this does not seem to be the place.
