Lolly Co Sr Web Developer UI User Experience HTML JavaScript PHP interview questions

I applied through remote.ok. Got an HR round call and was interviewed for 15 minutes by their HR. Got positive result and selected for next round which was a online coding test. I submitted the test with 100% correct answers. After that I didn't get any call or mail from the company. I tried to reach many times but no one replied on different different mails. Very unprofessional behaviour for a company who works in B2B. If you don't have budget or don't want to hire any candidate or anything, just communicate. Waiting for their mail for 1 month.
