Golang Reflect Get Type of Each Element of Slice

I'm have some confusion over golang reflect behaviour.

So basically I have a slice named src with type []interface{}. I would like to get the actual type of each element. This is what I did:

src := []interface{}{"noval", 0, nil}
srcType := reflect.ValueOf(src)

for i := 0; i < srcType.Len(); i++ {
    each := srcType.Index(i)

    if each.Interface() == nil {
        fmt.Println("value", each.Interface(), "is nil")
    } else {
        switch each.Kind() {
        case reflect.String:
            fmt.Println("value", each.Interface(), "is string")
        case reflect.Int, reflect.Int16:
            fmt.Println("value", each.Interface(), "is int")
        default:
            fmt.Println("value", each.Interface(), "is ?")
        }
    }
}

Output:

value noval is ?
value 0 is ?
value <nil> is nil

I don't understand why type of elements "noval" is not detected as string, instead the default is called from the switch.

Also the 0 value should be identified as reflect.Int but the default is called again.

Can somebody enlighten me please, thank you in advance.
