Pavlok interview questions

It was a pretty easy experience I first jumped on a call with somebody in their software department. There was a few hard questions but i studied up and I ended up answering them correctly. I was than asked to come in for a in person interview. The overall experience was less stressful than most interviews.

The Interview process is very unorganised and unprofessional. The interview process was of 5 day interview. First round was call interview in which about my past experience was asked and some general questions. The second round was good in which I was asked to work with UI designer and notes the flaws. The next two rounds were designing on boarding screens with UI designer, after which I was told that I am a good fit for this role and they will send out an appointment letter. After few day, I get email saying that CEO, who was not available throughout my interview process has now to test me on coding as well. So I agreed, moreover he didn't made it to office that day as well and I was asked to give a test. Which I gave and I consider it was good, but few days later I get an email saying that they couldn't hire me and that too with unreasonable reason. The only thing which pissed me off, was after being so patient with the whole unorganised process and working with them for 2 complete days, they first promise me to hire me and then didn't offer me the position. How so ever the product is, good or bad? I don't know, but the hiring process is definitely unprofessional.
