Submitted via job portal. I already had to answer situational questions before submitting my application. After a few days, a random number messaged me in Whatsapp asking me to fill out a Googlesheet. I verified through Linkedin if that person is a legit recruiter and told that recruiter to email me using the email I used in my application. The questionnaire had a lot of questions that are asked during an actual interview. After a few days of submitting my reply, I saw that I am no longer considered and the job posting was already closed. No official notification at all. Terrible and unprofessional experience.
