Tomorrow Biostasis interview questions

The interview process was lengthy 4-5 months, with significant delays between 4 stages. After having a no-show for 2 appointments with no prior reschedule, a 3rd rescheduled interview went well and covered technical topics in depth. However, I was never contacted again despite being told a final round would follow or a reply in 0.5-4 weeks. No feedback, no rejection despite enquires probably since extremely understaffed!. Overall, an experience that reflects poor coordination and low level or professionalism however what they are providing as a service or achieving is brilliant and worth researching regardless of the interview process.
