HelloFresh interview questions

3 rounds of interviews. Last interview was all shining roses and a very high recommendation from them that they are very interested and expect to receive a final interview. They sent a link for the final interview with the CIO. The link was broken. Checked the link on three different browsers and none worked. Reached out three times to two different people and they DO NOT have the courtesy to reply. Never received a notification about whether they were moving forward, about the broken link, about anything. They just GHOST you as though it's your problem that their system can't provide valid calendar interview links. I for one am very glad I never received an offer. This kind of treatment shows exactly how their software is broken and the managers have no regard for being professional at all!
