Algoriza Sr. FUll Stack Developer interview questions

Very bad HR and technical process They don't appreciate the candidate and his time. I had to take a vacation from my current job to do their interview, there are 3 interviews and all are technical on different days I don't know why this waste of time. I passed the interviews and they told me they will arrange with me the joining date. Then no body called me, and I called the bad HR many times through phone and whats app but with no answer. I never recommend it.
