When will Imperial Responddd???

Have you checked your junk/spam mail? According to Imperial's website, you should typically receive a response within 2 months of applying, however they are probably still assessing your application - I wouldn't worry about it.

Hey there!! I have applied for Master’s course named “Applied Biosciences and Biotechnology”. My application was completely submitted on 12th October. I received a mail on 22nd of October stating:- Your application has been received and has been sent to the respective department for consideration and if they want to take interview they will contact you something like that. Till now I haven’t heard back from them for interview or for offer.
