Securrency interview questions

Was contacted online by the recruiter. Had to do a type of interview where you video-record yourself. Got invited for a meeting a week later. However, they canceled an interview a day prior to it and sent me a technical task (without previous arrangements with me whatsoever, never bothered to check if I had free time to do it. ) They gave me 2-3 days timeline to finish it (In the middle of the week). I did solve the tasks, however, the second task had an obvious error (They were modifying it, but forgot to update comments or test cases) I finished the given tasks in time and fixed their errors. Noting in my own comments that their own tests will not work because I had to edit it. A day after they just replied with copy-pasted text saying they were not interested. I politely asked for more info, just in case I had missed something and made an error myself. But they never answer. My only conclusion is that they just ran the tests and never bothered to read my comments. So I guess that is not a good sign.

I wish I could put here a good feedback, but I cannot. I was processing on Senior DevOps engineer position, successfully went through HR and technical interviews. Technical interview was good, they asked me good and relevant questions. What is terrible is that I was waiting for a feedback around 2 weeks. I had an offer from other company, but I've declined it, because I had a feeling that Securency suits me best. What a mistake. After two weeks of promises to provide me any feedback, they sent me an offer. For Middle DevOps engineer position and 70% of salary on my previous job. I don't understand why they made me waiting such a long time and didn't tell me that I don't fit the position I was processing for. It's a really frustrating experience.
