Luno interview questions

Luno sent a link to book slot for a chat (possibly first round of interview). Chosen the slot however no confirmation was given, followed up through email but no replies. Would appreciate if automated rejection email is given at least, rather than being ghosted for no reason.

1. Someone on linkedIn contact me to participate with hiring process, 2. he invite me to google meeting to explain the position, tech-stack what i used before, and what tech-stack that Luno used currently. 3. On google meeting he ask me about current sallary, and how much sallary expectation to this company. 4. he invite me to next process (Online Test with HackerRank site)
