People Tech Group Java Developer interview questions

They wont take interview properly,basic java questions they asked me and after that they selected for Manager round and there manager won't ask any thing even I thought he don't Know anything about java.By looking at my resume it self he asked me how soon you can join? After the Hr discussion they told me that "you will get the offer letter by this weekend ".But 2 weeks completed.After 2 weeks I called them asked about my profile they simply said that "our Project is in Hold,Once we got the project we will release the offer". The real thing is that without having the projects they are conducting interviews and wasted our valuable time. So guys Don't prefer to even attend for Interview There.
