Blue Coding Full Stack Developer interview questions

I was contacted by a Blue Coding recruiter in 2023 January on my Linkedin about an ReactJS + NodeJS position. We had the first interview, general professional questions about my experience and a very nice interviewer. Then they asked me to do a technical Interview, which was a live coding session using React. I had to develop a simple GIF search application with Giphy API. Everything went well with the interview, and they informed me that they were expecting the client to confirm and schedule an interview with them. However, I never received any further response. Before that in May 2023 they contact me again on my email and said that this position was closed but they was looking for another developer on same company. They reengaging me in the process with another interview and the client asked me to do another code challenge, this was an specific project from them client using an Geolocation API for show forest maps. I sent the code and they never feedback me. Now the recruiter say for me in private he is no longer in the company anymore and they selected another candidate. It was really a waste of time since the company appears to not share the candidates from an old recruiter when they leave the company. I just wanted some feedback. I will no longer engage with interviews and challenges from this company again. Very disrespectful.
