Hi Minish
I think I have discovered the problem. The form on the site can update perfectly but when you see the output the format of the submission for the checkboxes with each option value in the array in a new line.
[INTERESTS] => Array
(
[75d797c631] => Array
(
[0] => 57718ea285 // this is output from the form
[1] => a27216269d
[2] => 13b937265f
[3] => 9b9da4f7c7
)

)
But the code you provided displays like:
[interests] => Array
(
[75d797c631] => Array
(
[0] => 57718ea285, a27216269d, 13b937265f, 9b9da4f7c7. // all the versions you suggested print all the options in one line
)

)

How can I get each option on a new line?

I was able to create the array properly and match the form version with the following snippet but mailchimp still does not update so I'm pretty well stumped at this point.

add_filter( 'mc4wp_user_sync_subscriber_data', function( \MC4WP_MailChimp_Subscriber $subscriber, \WP_User $user ) {

$list=types_render_usermeta("position-type", array("user_id" => $user->ID,"state"=>"checked"));
$list = explode( ',', $list) ;
$subscriber->merge_fields['INTERESTS']['75d797c631'] = $list;
return $subscriber;

}, 10, 2 );
