Anicca Data Senior Software Engineer interview questions

Apparently there was no one available to do technical screening in the Americas and I went through 2 technical screenings conducted by engineers in India. The technical screens were pretty easy (leetcode easy or easier). After passing, I received an email stating they'd like to extend an offer and then a week later a phone call confirming they want to extend an offer along with the offer details. However, 2+ weeks later I never received the offer letter and I was ghosted over both email and phone call when I attempted to reach out. It's like the company just entirely disappeared. Candidates beware if applying for a position with this company.
