Shell Recharge Solutions Software Developer interview questions

Applied and was asked for my availability for an initial interview. Sent my availability but received no response until I double checked. Interview was planned, but once I joined the interviewer didn’t show up. Waited for 15 minutes. Send another email to ask if something went wrong during planning. Maybe the interview time was for another time zone, for example. It’s been a couple of days. Haven’t received a reply to this mail.
