Ericsson interview questions

Got a screening mail from HR. Responded with all details but never heard back for the next round 4 months. The HR said hiring manager didn't respond. Then I saw another posting and reached out to the same HR and she recommended me to a 3rd position. I wasn't confident about the role but still went ahead. The interview was for 30mins with the Manager and 2 technical team members. Basic questions about networking and my problem solving technique. Got the offer letter next day.
