Genesys Software Engineer Internship interview questions

The interview was scheduled for Jan 26, 2019. I was interviewed by the Manager and Staff Engineer. Interview questions are more asking background and what I specialize in. I gave my best in the interview answering all the questions they asked. It is weird that they didn't even take care to respond back after the interview. It is a SHAME. It is an HR responsibility to give feedback on whether rejection or not. I waited for 3 weeks and still no response. I called HR and it seems that they don't even know me that I was interviewed. There was no formal explanation of rejection or email. It is a SHAME.

Not particularly difficult interview process, I received a call from a recruiter after I received an internal referral. I was interviewed by my current manager (senior software engineer) and a staff software engineer about fundamental object oriented language concepts, such as the advantages and disadvantages of using linkedlists vs arrays and so forth. What access levels does public and global provide etc. and more questions like that. I also had ML on my resume, and I was asked about some fundamental ML questions such as what is an LSTM, explain how a perceptron works, what is forward and back propogation, and so forth. It seems like they will ask you technical questions around what your resume says, but will not ask you to do data structures and algorithms questions, which is a little different from many other companies. I simply had one phone call and I received an offer.
