Set order for product Collection in magento2

Question

I am filtering product collection like below.

    $productSkuString = 'O, C, D, A, F, S';
        $productSkus = explode(', ', $productSkuString); 
        $collection = $this->collectionFactory->create()
        ->addAttributeToSelect('*')
        ->addAttributeToFilter(
                'sku', array('in' => $productSkus)
        )           
        ->setStoreId(0)
        ->load();
        return $collection;

The above code filtering the product collection with mentioned skus. but not in the same order of the sku.

I need to load the product with same order where the sku is mentioned.

Currently its loading the product in random order.

Can anyone look into it and update me please

Use setOrder as below to sort product collection

 $productSkuString = 'O, C, D, A, F, S';
 $collection = $this->collectionFactory->create()
        ->addAttributeToSelect('*')
        ->addAttributeToFilter(
                'sku', array('in' => $productSkus)
        )           
        ->setStoreId(0)
        ->setOrder(new Zend_Db_Expr("FIND_IN_SET('sku', ".$productSkuString.") ASC"))
        ->load();

$collection = $this->collectionFactory->create()
        ->addAttributeToSelect('*')
        ->addAttributeToFilter(
                'sku', array('in' => $productSkus)
        )           
        ->setStoreId(0)
        ->setOrder('sku','ASC')
        ->load();
