Skillfield interview questions

Interview includes some basic SQL knowledge and visualization tools. Interviewer may require you to send a link about your projects, and I would say the experience is quite professional, but the response is quite slow.

Was told to send some available times for the phone screen. Sent my availability immediately and there was no response. Sent another email again and said call me anytime. No response. Sent linkedin message to tell the recruiter to check email. No response. Never heard from the recruiter at all.
