I applied late last year in October for the 2019 class. I received an email in February 2019 that my application would be put on hold " pending possible future interview invitation." I was reached out to again in May of this year with questions about a class I had taken. Someone had reached out to me in October 2018 with the same question so I assumed my application was being recirculated for the 2020 class. I received an invite to interview back in August of this year for 2020. I think you have a chance to still interview for 2020 since interviews are just beginning. It just depends on how quickly they fill the program. I was told last year that interviews go until the program is filled which could be as early as October or as late as January (keep in mind that was 2018 for a 2019 start and interviews began in July 2018... interviews are taking place later this year). And if you do not receive an invite to interview for 2020, then your application may likely be rolled over to 2021.
