Airtower Networks interview questions

Received an email to set up an initial phone call, replied with the times i was available. The recruiter set up the time. The call lasted about 5 min she seemed as if she was in a rush to get off the phone I answered a few questions, told her about my background. she then asked me when a good time was to have an actual interview with the hiring manager. I gave her all times i was available she said see will email me with the time info. After that i was basically ghosted and never received and emails for calls from them it has now been 3 weeks

Easy, they just walk through your resume and your past professional experience. The company wants to know how much of relation can you make between theoretical knowledge and hands on and your ability and willingness to learn
