Interacted with but ghosted? after assesment

I'm very tired of this clients na magpapagawa ng tasks for assesmnent sa mga inaaplayan ko sa OLJPH and Upwork. 1 month of applying luckyly i got 2 message 1 for Upwork and 1 for OLJPH. Sa upwork na send ko na ung assesment na graphic need nila but i feel parang ighoghoat din yata ako katulad nung isang nag message sakin from OLJPH saying na after I send the assessment for graphic design eh sabi nia gusto daw nia ako iinterview then tinanong ano availabblity ko I send reply but its been 1 week na wala parin akong nakukuhang response from my last chat. I feel like my effort was really burn by this online assesment pag may client message I feel tuloy na should I chnage to virtual assesment role na lang ksi I really disheartened without knowing why they ghosted my works after submitting them. Anyone may experience din bang ganto ?? In really newbee sa Freelancing since remote jobs ako at need ko talaga ng extra income since super baba ng sahod ko now
