FileCloud Frontend Engineer interview questions

I applied at March. After 2 weeks I got scheduled a technical interview. It was alright, I answered the questions and successfully did the task. I got informed it was ok and that I'd be informed with next steps shortly after. But after 2 weeks of radio silence I sent an email about what's the status of my application, and only shortly after I was informed they decided not to proceed me any further.

I was invited for a 30min technical interview with the tech lead and an engineer, they had some classic javascript & web accessibility questions (if you google "top 10 js questions" you got it). I was training for a presentation meeting, but I was a surprised that they said the meeting would be a technical interview, since the HR were not explicit about it, and it was my first contact with the company. PS: What frustrated me most about the process was that I had asked HR when the next stage of the process would happen and what it would be like (a technical or presentation interview), and I didn't get an answer. It definitely compromised my process.
