GoodRx Full Stack Engineer interview questions

Recruiter reached me on LinkedIn. Had an intro call with the Recruiter. Then, I was scheduled a phone call with the Hiring Manager. This round contained both technical and behavioral questions. The technical section included basic JavaScript concepts & Microservices concepts. Overall, the interview questions were good. The interviewer was communicating well. He gave me a feedback for the next steps will be a take home challenge and on clearing it will be virtual onsite with multiple coding rounds testing JS knowledge and some cultural behavioral rounds. The next day I was informed by the recruiter that I had been rejected. Overall, I am very much dissatisfied with the interviewer. I do not understand why these hiring managers give false hopes by saying a positive feedback and then rejecting within 24 hours. Kindly, I request these people not to waste the candidate's time as we are also managing office work and giving a lot of efforts for the interviews. It is not easy. Finally, I would not recommend this company to others unless if you want to waste your time for nothing.
