Sonder Software Developer interview questions

technical phone screen a few rounds of interviews leetcode type style question then system design type style question overall decent experience interviewing with them not the hardest i have had, faang interviews are definitely a little harder

I applied and received an invitation to talk. Chose date from the calendar. At this time I didn't received any call, email or message. just ignore. Then I emailed to an HR and received no email, no message, no call and just ignore again.
