Deltax interview questions

Aptitude test, typing test and then a face to face interview where they ask guesstimate questions and check how you communicate and how your mind works- how analytical you are

I had attended the initial assessment it had three rounds, some aptitude, some english grammar, and some calculations where we can use excel or spreadsheet, and english comprehension where we have to hear the audio and choose the correct answer among the options, finally they play a video then we have to choose the correct option among them. All questions were MCQ questions. Unfortunately they rejected me, for the reason I don't know. And the assessment is not monitored.
