Good Course; Suggest Providing Recorded Classes
“Overall, it was good, no doubt about it. But one thing you guys can do for the candidates’ favor is to provide at least 3-4 recorded classes so that we can complete the course. As you know, these days there are a lot of network issues and we are also working. So if you can do that, your course will be 100 percent beneficial for us. Thank you.”
