Oktopost interview questions

Overly complicated process: 20 min interview with recruiter -> 45 min interview with director -> 1 hour mock demonstration -> Timed personality test -> 45 min interview with CPO -> 30 min meet and greet in-office. Each interview repeated the same questions, and no feedback was given at any stage. 3-days in-office, 2 at home with no set working hours or days. I'm not sure why the role isn't remote considering these weren't set; you could just pick days your colleagues aren't there, making it pointless. I could not get an answer on set working hours or days either, just told that it is "flexible" and that people are "measured on outcome, not by hours worked". Similarly, the recruiter couldn't answer me on their annual leave policy, just again, that they're "flexible". The role itself is not what the job specification describes and is quite odd for such a small organisation - Assisting users on how to use your assigned module and when needed, demonstrating the area to existing customers. There's no discovery process for additional modules or a clear route for onboarding. It's a weird mix of a service-desk/professional-service role, not solutions. The salary was £50k, which is £10k below the market minimum for a solutions consultant role in London. I was told not to waste their time as there wouldn't be any room for negotiation. I asked about subsidised travel as it's London and many jobs offer this, but was told there's a $100 a month (no idea why they used $ instead of £) expense account that I could use, although anyone that knows London knows that is barely enough to cover a few days.
