Harris Computer Full Stack Web Developer interview questions

Process was supposed to be 1 with the manager , 1 with the leader and 1 with HR , did one with the manager who was nice but I did not recieve any follow up or response despite me sending a follow up email few weeks later. I did not even recieve an automatic email saying that the offer is now closed ( i had to check periodically on the website ) , this happened for 2 other offers too
